x in (-oo:+oo)
(5/2)*(-4*x-2) = (3/4)*x+6 // - (3/4)*x+6
(5/2)*(-4*x-2)-((3/4)*x)-6 = 0
(5/2)*(-4*x-2)+(-3/4)*x-6 = 0
5/2*(-4*x-2)+(-3*x)/4-6 = 0
(5/2*4*(-4*x-2))/4+(-3*x)/4+(-6*4)/4 = 0
5/2*4*(-4*x-2)-3*x-6*4 = 0
-43*x-24-20 = 0
-43*x-44 = 0
(-43*x-44)/4 = 0
(-43*x-44)/4 = 0 // * 4
-43*x-44 = 0
-43*x-44 = 0 // + 44
-43*x = 44 // : -43
x = 44/(-43)
x = -44/43
x = -44/43
