im assuming you meant 2x + y = 6 instead of 2x = y = 6

answer:
x = 14/3
y = -10/3

step by step explanation:
2x + y = 6
x + 2y = -2
solve for y in the first equation
y = 6 - 2x
plug y into the second equation
x + 2(6 - 2x) = -2
-3x + 12 = -2
-3x = -14
x = 14/3
plug into the y equation
y = 6 - 2(14/3)
y = -10/3
