x in (-oo:+oo)
(3/4)*(5*x+2) = 2*(3-(4*x))+19 // - 2*(3-(4*x))+19
(3/4)*(5*x+2)-(2*(3-(4*x)))-19 = 0
(3/4)*(5*x+2)-2*(3-4*x)-19 = 0
3/4*(5*x+2)-2*(3-4*x)-19 = 0
3/4*(5*x+2)-2*(3-4*x)-19 = 0
47/4*x-19-9/2 = 0
47/4*x-47/2 = 0
47/4*x-47/2 = 0
47/4*x-47/2 = 0 // + 47/2
47/4*x = 47/2 // : 47/4
x = 47/2/47/4
x = 2
