-6 + 6 = 0
0 + -2x = 12 + 6 -2x = 12 + 64x+2(x-3)=8x+12 is our main problem right? so... 4x + (-3 * 2 + x * 2) = 8x + 12
4x + (-6 + 2x) = 8x + 12 So next we do: -6 + 4x + 2x = 8x + 12 Reorder the terms :) -6 + 6x = 12 + 8x Now were going to solve for x -6 + -2x = 12 + 8x + -8x 8x + -8x = 0
-6 + -2x = 12 + 0
-6 + -2x = 12 -6 + 6 = 0 0 + -2x = 12 + 6
-2x = 12 + 6= -2x = 18 so now were just going to divide each side by -2 and so thats going to be like this -2x = 18 / -2 /-2 0 -9 so whats left over is x = -9 So your answer is A.
