y in (-oo:+oo)
(4/5)*y-(2*(y-4)) = 3*y-15 // - 3*y-15
(4/5)*y-(2*(y-4))-(3*y)+15 = 0
(4/5)*y-2*(y-4)-3*y+15 = 0
(4*y)/5-2*(y-4)-3*y+15 = 0
(-2*5*(y-4))/5+(4*y)/5+(-3*5*y)/5+(5*15)/5 = 0
4*y-2*5*(y-4)-3*5*y+5*15 = 0
40-6*y-15*y+75 = 0
40-21*y+75 = 0
115-21*y = 0
(115-21*y)/5 = 0
(115-21*y)/5 = 0 // * 5
115-21*y = 0
115-21*y = 0 // - 115
-21*y = -115 // : -21
y = -115/(-21)
y = 115/21
y = 115/21
