You can substitute the expression for y given by the first equation into the second equation.

2x + 6 = y = 1/2x - 6

4x + 12 = x - 12 (multiply by 2)

3x + 12 = -12 (subtract x)

3x = -24 (subtract 12)

x = -8 (divide by 3)

y = 2(-8) + 6 (substitute for x in the first equation)

y = -16 + 6 (do the multiplication)

y = -10 (do the addition)

**The solution is (x, y) = (-8, -10)**.
