Answer: The correct answer is x=1/2, y=3

Explanation:

Using substitution, solve first for y:

2x - y = -2

-y = -2 - 2x

y = 2 +2x

Substitute the y value in the first equation:

4x + 3 (2x +2) = 11

4x + 6x + 6 = 11

10x = 11 - 6

10x = 5

x = 5/10 = 1/2

Substitute the x value in the second equation:

2 (1/2) - y = -2

1 - y = -2

-y = -3

y = 3
