x-3 = 0
x-3 = 0
x-3 = 0 // + 3
x = 3
x in (-oo:3) U (3:+oo)
5/(x-3) = 5/12 // - 5/12
5/(x-3)-(5/12) = 0
5/(x-3)-5/12 = 0
(5*12)/(12*(x-3))+(-5*(x-3))/(12*(x-3)) = 0
5*12-5*(x-3) = 0
75-5*x = 0
(75-5*x)/(12*(x-3)) = 0
(75-5*x)/(12*(x-3)) = 0 // * 12*(x-3)
75-5*x = 0
75-5*x = 0 // - 75
-5*x = -75 // : -5
x = -75/(-5)
x = 15
