x in (-oo:+oo)
(1/3)*(x-8)-((7/2)*(5*x-5)) = 7/12 // - 7/12
(1/3)*(x-8)-((7/2)*(5*x-5))-(7/12) = 0
(1/3)*(x-8)+(-7/2)*(5*x-5)-7/12 = 0
1/3*(x-8)-7/2*(5*x-5)-7/12 = 0
(1/3*12*(x-8))/12+(-7/2*12*(5*x-5))/12-7/12 = 0
1/3*12*(x-8)-7/2*12*(5*x-5)-7 = 0
178-206*x-7 = 0
171-206*x = 0
(171-206*x)/12 = 0
(171-206*x)/12 = 0 // * 12
171-206*x = 0
171-206*x = 0 // - 171
-206*x = -171 // : -206
x = -171/(-206)
x = 171/206
x = 171/206
