x in (-oo:+oo)
(2/5)*(3*x+3) = 2*(3-(2*x))+16 // - 2*(3-(2*x))+16
(2/5)*(3*x+3)-(2*(3-(2*x)))-16 = 0
(2/5)*(3*x+3)-2*(3-2*x)-16 = 0
2/5*(3*x+3)-2*(3-2*x)-16 = 0
2/5*(3*x+3)-2*(3-2*x)-16 = 0
26/5*x-16-24/5 = 0
26/5*x-104/5 = 0
26/5*x-104/5 = 0
26/5*x-104/5 = 0 // + 104/5
26/5*x = 104/5 // : 26/5
x = 104/5/26/5
x = 4
x = 4
