x in (-oo:+oo)
(1/4)*(x-2)+(1/2)*(3*x-1) = (1/8)*(x+1) // - (1/8)*(x+1)
(1/4)*(x-2)+(1/2)*(3*x-1)-((1/8)*(x+1)) = 0
(1/4)*(x-2)+(1/2)*(3*x-1)+(-1/8)*(x+1) = 0
1/4*(x-2)+1/2*(3*x-1)-1/8*(x+1) = 0
1/4*(x-2)+1/2*(3*x-1)-1/8*(x+1) = 0
7/4*x-1/8*x-1-1/8 = 0
13/8*x-9/8 = 0
13/8*x-9/8 = 0
13/8*x-9/8 = 0 // + 9/8
13/8*x = 9/8 // : 13/8
x = 9/8/13/8
x = 9/13
x = 9/13
