x in (-oo:+oo)
(3/4)*(2*x+2) = 4*(3-(2*x))+18 // - 4*(3-(2*x))+18
(3/4)*(2*x+2)-(4*(3-(2*x)))-18 = 0
(3/4)*(2*x+2)-4*(3-2*x)-18 = 0
3/4*(2*x+2)-4*(3-2*x)-18 = 0
3/4*(2*x+2)-4*(3-2*x)-18 = 0
19/2*x-18-21/2 = 0
19/2*x-57/2 = 0
19/2*x-57/2 = 0
19/2*x-57/2 = 0 // + 57/2
19/2*x = 57/2 // : 19/2
x = 57/2/19/2
x = 3
x = 3
