(1/2)*(4*x+6)-((1/4)*(8*x-12)) = (1/2)*(2*x-4) // - (1/2)*(2*x-4)
(1/2)*(4*x+6)-((1/4)*(8*x-12))-((1/2)*(2*x-4)) = 0
(1/2)*(4*x+6)+(-1/4)*(8*x-12)+(-1/2)*(2*x-4) = 0
1/2*(4*x+6)-1/4*(8*x-12)-1/2*(2*x-4) = 0
1/2*(4*x+6)-1/4*(8*x-12)-1/2*(2*x-4) = 0
2-x+6 = 0
8-x = 0
8-x = 0
8-x = 0 // - 8
-x = -8 // * -1
x = 8
x = 8
