x in (-oo:+oo)
-21/2 = (-5/8)*(x+32)+6/8 // - (-5/8)*(x+32)+6/8
-((-5/8)*(x+32))-21/2-(6/8) = 0
(5/8)*(x+32)-21/2-3/4 = 0
5/8*(x+32)-21/2-3/4 = 0
(5/8*2*4*(x+32))/(2*4)+(-21*4)/(2*4)+(-3*2)/(2*4) = 0
5/8*2*4*(x+32)-21*4-3*2 = 0
5*x-6+76 = 0
5*x+70 = 0
(5*x+70)/(2*4) = 0
(5*x+70)/(2*4) = 0 // * 2*4
5*x+70 = 0
5*x+70 = 0 // - 70
5*x = -70 // : 5
x = -70/5
x = -14
x = -14
