x in (-oo:+oo)
(1/2)*(x+2)-((1/4)*(x-8)) = x+6 // - x+6
(1/2)*(x+2)-((1/4)*(x-8))-x-6 = 0
(-1/4)*(x-8)+(1/2)*(x+2)-x-6 = 0
1/2*(x+2)-1/4*(x-8)-x-6 = 0
1/2*(x+2)-1/4*(x-8)-x-6 = 0
1/4*x-x-6+3 = 0
3-3/4*x-6 = 0
-3/4*x-3 = 0
-3/4*x-3 = 0
-3/4*x-3 = 0 // + 3
-3/4*x = 3 // : -3/4
x = 3/(-3/4)
x = -4
x = -4
