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