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)
