x in (-oo:+oo)
4-(2*(3*x-(1/2))) = 5*x-((1*2)/3) // - 5*x-((1*2)/3)
(1*2)/3-(2*(3*x-(1/2)))-(5*x)+4 = 0
2/3-2*(3*x-1/2)-5*x+4 = 0
(-2*3*(3*x-1/2))/3+(-5*3*x)/3+2/3+(3*4)/3 = 0
3*4-2*3*(3*x-1/2)-5*3*x+2 = 0
2-33*x+3+12 = 0
5-33*x+12 = 0
17-33*x = 0
(17-33*x)/3 = 0
(17-33*x)/3 = 0 // * 3
17-33*x = 0
17-33*x = 0 // - 17
-33*x = -17 // : -33
x = -17/(-33)
x = 17/33
x = 17/33
