@abraham i dont agree with you, and beside how did you arrive at you answer!!!

Well this is my solution to the equation.

From the above equation, if u substitute y with 2. The equation becomes

2= (1/2 * x ) + 6

therefore 2 = x/2 + 6

==> 2 = x + 12/2

==> cross multiply the resulting equation. You will get

x + 12 = 4

x = 4 - 12

x = -8
