Answer: y = -11/4 and x=3

Explanation:

I think you asked me to find x and y

-7x+4y=-32 and 9x -2y=38

group x and y on one side

[(-7x+4y)+(9x-2y)=-32+38]

2x+2y=6

now let do x first

2x=6

x=3{ 2 divided by 6}

To find y,

-7x+4y=-32 and 9x -2y=38

put x value 3 in all x place

-7x + 4y = -32

-7(3) + 4y = -32

-21 + 4y = -32

4y = -32 + 21

4y = -11

y = -11/4

I hope this helps you.
