x in (-oo:+oo)
(3/8)*(x-(2/3))+(1/4)*(x+3) = (1/2)*(x-5) // - (1/2)*(x-5)
(3/8)*(x-(2/3))+(1/4)*(x+3)-((1/2)*(x-5)) = 0
(3/8)*(x-2/3)+(1/4)*(x+3)+(-1/2)*(x-5) = 0
3/8*(x-2/3)+1/4*(x+3)-1/2*(x-5) = 0
3/8*(x-2/3)+1/4*(x+3)-1/2*(x-5) = 0
5/8*x-1/2*x+1/2+5/2 = 0
1/8*x+3 = 0
1/8*x+3 = 0
1/8*x+3 = 0 // - 3
1/8*x = -3 // : 1/8
x = -3/1/8
x = -24
x = -24
