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

Multiply the first equation by 2
8x+2y=12
Add it to the second equation
9x=18
Now you know x=2
Plug that into equation two
(2)-2y=6
Add 2y to both sides of the equation
2=6+2y
Subtract 6 from both sides of the equation
2-6=2y
-4=2y
-2=y

4x+y=6
x-2y=6

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

8x+2y=12
X-2y=6

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.

Done

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

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

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

8x+2y=12
Add it to the second equation
9x=18
Now you know x=2

2=6+2y

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

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)).

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

yeah but I just don't understand how to solve it

4x+y=6

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.

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?

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?

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

don't know

maybe 666

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

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?
