So all sides myst be equal
3x+2 = 2y-x = y +3
taking the last two:
2y-x = y +3
y = x+3
sub that into:
3x+2 = 2y-x
4x = 2y - 2
2x = y - 1
2x = x+3 - 1
x = 2
sub back into above to find y
3x+2 = 2y-x = y +3
taking the last two:
2y-x = y +3
y = x+3
sub that into:
3x+2 = 2y-x
4x = 2y - 2
2x = y - 1
2x = x+3 - 1
x = 2
sub back into above to find y
