Question

I don’t know how to do it.

Answer 1

X= 0

Y= 2

Explanation:

Use the elimination method.

Multiply the bottom row by negative one.

That will result in the same top but -x-2y=-4 on the bottom.

Add them together and you will get -4x= 0

X=0

Plug x in to find y. Make sure it works for both.

0+ 2(2)=4

2(2)=4

4=4

-3(0)+2(2)= 4

2(2)=4

4=4

Since it works for both, y=2
