d in (-oo:+oo)
(1/2)*(d-9)-((8/3)*(5*d-2)) = 5/12 // - 5/12
(1/2)*(d-9)-((8/3)*(5*d-2))-(5/12) = 0
(1/2)*(d-9)+(-8/3)*(5*d-2)-5/12 = 0
1/2*(d-9)-8/3*(5*d-2)-5/12 = 0
(1/2*12*(d-9))/12+(-8/3*12*(5*d-2))/12-5/12 = 0
1/2*12*(d-9)-8/3*12*(5*d-2)-5 = 0
10-154*d-5 = 0
5-154*d = 0
(5-154*d)/12 = 0
(5-154*d)/12 = 0 // * 12
5-154*d = 0
5-154*d = 0 // - 5
-154*d = -5 // : -154
d = -5/(-154)
d = 5/154
d = 5/154
