x in (-oo:+oo)
(1/5)*(x+4) = 3*x-(2*(1-x))-2 // - 3*x-(2*(1-x))-2
(1/5)*(x+4)+2*(1-x)-(3*x)+2 = 0
(1/5)*(x+4)+2*(1-x)-3*x+2 = 0
1/5*(x+4)+2*(1-x)-3*x+2 = 0
1/5*(x+4)+2*(1-x)-3*x+2 = 0
2-9/5*x-3*x+14/5 = 0
2-24/5*x+14/5 = 0
24/5-24/5*x = 0
24/5-24/5*x = 0
24/5-24/5*x = 0 // - 24/5
-24/5*x = -24/5 // : -24/5
x = -24/5/(-24/5)
x = 1
x = 1
