Could someone please walk me through on how to answer this?

help is deeply appreciated

I'm not sure how your textbook got from 2x-3y=-24 to x+6y=18, but I don't think that's correct. Mainly because x+6y=18 would be simplified to x+y=3 which is different from the answer shown above.

I'm really sorry I couldn't help, maybe I misread something? Maybe something was mentioned that I couldn't see in the picture?

(っ◔◡◔)っ ♥ Hope this helped! Have a great day! :) ♥

Please, please give brainliest, it would be greatly appreciated, I only need one more before I advance, thanks!

The answer should be x= -6 and y= 4

I’m going to attempt to explain...

In your first equation, solve for x

This will give you x= 3/2y - 12

Take this and input it in for x in the second equation. This will end up solving for y.

It will look like :

3/2y-12+6y=18

I hate working with fractions, so I like to get rid of them. You do this by multiplying each term by the denominator- in this case it’s 2.

It’ll come out to
3y-24+12y=36

15y-24=36
15y=60
y=4

Take this new y value and input into your original 2nd equation

x+ 6(4)= 18
x+24=18
Subtract 24 from each side
x= -6
