x in (-oo:+oo)
(3/4)*(3*x-(1/2))-(2/3) = 1/8 // - 1/8
(3/4)*(3*x-(1/2))-(2/3)-(1/8) = 0
(3/4)*(3*x-1/2)-2/3-1/8 = 0
3/4*(3*x-1/2)-2/3-1/8 = 0
(3/4*3*8*(3*x-1/2))/(3*8)+(-2*8)/(3*8)+(-1*3)/(3*8) = 0
3/4*3*8*(3*x-1/2)-2*8-1*3 = 0
54*x-25-3 = 0
54*x-28 = 0
(54*x-28)/(3*8) = 0
(54*x-28)/(3*8) = 0 // * 3*8
54*x-28 = 0
54*x-28 = 0 // + 28
54*x = 28 // : 54
x = 28/54
x = 14/27
x = 14/27
