x in (-oo:+oo)
(1/5)*(x+2) = 3*x-(4*(3-x))-8 // - 3*x-(4*(3-x))-8
(1/5)*(x+2)+4*(3-x)-(3*x)+8 = 0
(1/5)*(x+2)+4*(3-x)-3*x+8 = 0
1/5*(x+2)+4*(3-x)-3*x+8 = 0
1/5*(x+2)+4*(3-x)-3*x+8 = 0
8-19/5*x-3*x+62/5 = 0
8-34/5*x+62/5 = 0
102/5-34/5*x = 0
102/5-34/5*x = 0
102/5-34/5*x = 0 // - 102/5
-34/5*x = -102/5 // : -34/5
x = -102/5/(-34/5)
x = 3
x = 3
