What the fuck is the answer to this Posted on May 25, 2023 by Anonymous What the fuck is the answer to this
please someone help it's a timed test
The first one dumbass
IDK I AM A FUCKING RETARD LOLOLOL
all of the replies to this is making me realize I'm probably retarded. I'm like 18 and have no idea what this shit is about
My point was that you don't have to be good at math. You just have to be good at making a computer do math.
ChatGPT with a Wolfram Alpha plugin is going to be fucking amazing.
Did you not go to school? I feel like you could infer the answer with nothing but the understanding that numbers exist and can be represented by letters
yeah but I just don't understand how to solve it
doesn't make sense cause I can't make x into a number and get 6 out of 4. so even if I were to imply I have to multiply I can't fix 6 into 4
You are supposed to solve for x or y first, retard. Using both equations to cancel one of them out.
can you give a step by step example of how you did that then. cause it sounds impossible
Look at my post here
This is actually so easy you can solve it in your head, but just follow this guide retard.
I solved using substitution.
These anons solved by elimination. Either way works, but people often avoid substitution so you don't have to fuck around with fractions.
there's way too many rules and steps to this shit and theres too many words i dont understand.
can solve it in your head my ass... I have to count on my fingers if I'm doing multiplication everytime
but I guess I understand??? doubt I'll remember it
you can just do it the brute force way: combine terms, pluggin values.
4x + y = 6
x - 2y = 6
5x - y = 12
Lmao what? You are dion waiters levels of retarded. Please tell me you are in high school and not in community college
1. You multiply or divide one equation by the number that would make x or y equal to the other. I will do the first equation so:
2(4x+y=6) so that in turns into
2. Now that y shares the same coefficient, you cancel them out by putting the two equations together. It turns into
9x = 18.
3. You solve for x which is 2.
4. Solve for y using the x value you found which equals -2.
it's a multiple choice question, the options tip you off as to what it will be already. Just go through the options and you'll see why it works.
What will the answer to 4x + y be if x is 2 and y is -2?
You might be beyond help. First off 4 times 1.5 is 6. Second its clear you have no idea what the fuck is going on by the fact you ignored an entire variable
this nigga getting his GED or is literally 12.
you are retarded and you shouldn't be proud of it.
A double negative is a positive you literal sixth grader...
are you 7 years old?
Genuine question, can you explain why something like this is confusing for you? Do you understand what it's asking but you struggle somewhere along the way to solving it, or does the question just basically read as gibberish to you because you don't understand what it's asking?
LMAO nigga I did that shit in my head and I got the answer. It is the first one. I thought you were supposed to be over 18 to post on LULZ. Makes sense why China will be taking over
>haven't done any proper math in over half a decade
>have no idea what I'm looking at
>feels like trying to decipher another language
Multiply the first equation by 2
Add it to the second equation
Now you know x=2
Plug that into equation two
Add 2y to both sides of the equation
Subtract 6 from both sides of the equation
This test is retarded. You could just replace the values in the answer into the equation until they're equals to the other side and brute force an A. American education is a disgrace
At my high school, we had to show our work on the page or else we wouldnt get full points. Sometimes it was just a blank page with the question and we had to do it all by hand
This shit is the reason I dropped out from engineering after wasting 2 years.
Brailet here ama
lol you niggas wanna post shit about IQ and then have a 100 post thread about basic system of equations
You dumb nagger. Solve for y in one equation and then plug that into y in the other equation. now solve for x
I think I can do this but I'm on mobile and it would take time. In other words fuck you OP figure it out yourself.
If you can't do this in your head, especially when it's multiple choice, you are beyond fucking retarded.
so many 500iq big brains in the thread right now ooo
It's a 6th grade math problem anon. Not even post commie country 6th grade.
ok let's see if i still remember linear algebra well...
4x + y = 6
x - 2y = 6
so that means...
> x - 2y = 6
> x = 6 + 2y
ok stash that, replace x on the other equation...
> 4x + y = 6
> 4(6 + 2y) + y = 6
> 24 + 8y + y = 6
> 24 + 9y = 6
> 9y = 6 - 24 = -18
> y = -18 / 9
> y = -2
ok we got y, now for x on the other equation
> x - 2y = 6
> x - 2 * (-2) = 6
> x + 4 = 6
> x = 6 - 4 = 2
aye, that's the solution alright
My dear retarded anon, I suspect that you are underage, in which case please never come back here again (or at the very least do not come back here until you are 18 years of age). If this is not bait, though, you should genuinely pick up a math book, you can dew it.
I can teach you some really basic math before I fuck off from this thread, by the way;
When you move a number/letter to the other side of the equal, you change it's sign.
Letters can hold other letters and numbers, think of them as placeholders.
If you multiply something which has a sign (+/-) that sign can change the sign of what you are multiplying (i.e. -2*4 = -8 (NOT 8)).
Listen to L's theme from the hit anime "Death Note", it has been proven to increase your iq by 3 standard deviations, while also increasing your penis size by 4 inches.
literally just plug in the numbers into the equation JESUS FUCKING CHRIST
Literally just plug the answers into x and y and solve. Are you retarded?
