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