see below

Explanation:

The equations are

1.) 2x+y=1
2.) x−(−2y)=−7 that gives x+2y=−7
put some values for x in each equation to get corresponding values for y in each equation

like in equation 1
let x=1
2(1)+y=1
y=1−2
y=−1
similarly put another values for x and you will get corresponding values for y .
(if you want me to add those values in answer just mention once in comments , i'll update the answer)
