Answer 1

x=0 and y=−2

keep scrolling it is kind of long

Explanation:

−2x+2y=−4,3x−2y=4

−2x+2y=−4for x:

−2x+2y=−4

−2x+2y+−2y=−4+−2y

−2x=−2y−4

-2x/-2=-2y-4/-2

x=y+2

Substitute y +2 for x in3x−2y=4:

3x−2y=4

3(y+2)−2y=4

y+6=4

y+6+−6=4+−6

y=−2

Substitute −2 for y in x=y+2:

x=y+2

x=−2+2

x=0

x=0 and y=−2
