x in (-oo:+oo)
(1/6)*(x+3) = 3*x-(5*(3-x))-8 // - 3*x-(5*(3-x))-8
(1/6)*(x+3)+5*(3-x)-(3*x)+8 = 0
(1/6)*(x+3)+5*(3-x)-3*x+8 = 0
1/6*(x+3)+5*(3-x)-3*x+8 = 0
1/6*(x+3)+5*(3-x)-3*x+8 = 0
8-29/6*x-3*x+31/2 = 0
8-47/6*x+31/2 = 0
47/2-47/6*x = 0
47/2-47/6*x = 0
47/2-47/6*x = 0 // - 47/2
-47/6*x = -47/2 // : -47/6
x = -47/2/(-47/6)
x = 3
x = 3
