x in (-oo:+oo)
(1/3)*(x+2) = 9*x-(4*(1-x))-8 // - 9*x-(4*(1-x))-8
(1/3)*(x+2)+4*(1-x)-(9*x)+8 = 0
(1/3)*(x+2)+4*(1-x)-9*x+8 = 0
1/3*(x+2)+4*(1-x)-9*x+8 = 0
1/3*(x+2)+4*(1-x)-9*x+8 = 0
14/3-11/3*x-9*x+8 = 0
14/3-38/3*x+8 = 0
38/3-38/3*x = 0
38/3-38/3*x = 0
38/3-38/3*x = 0 // - 38/3
-38/3*x = -38/3 // : -38/3
x = -38/3/(-38/3)
x = 1
x = 1
