x-3 = 0 // + 3
x = 3
x in (-oo:3) U (3:+oo)
3/(x-3) = x/(x-3)-(3/2) // - x/(x-3)-(3/2)
3/(x-3)-(x/(x-3))+3/2 = 0
3/(x-3)+(-1*x)/(x-3)+3/2 = 0
(2*3)/(2*(x-3))+(-1*2*x)/(2*(x-3))+(3*(x-3))/(2*(x-3)) = 0
3*(x-3)-1*2*x+2*3 = 0
3*x-2*x-9+6 = 0
x-3 = 0
(x-3)/(2*(x-3)) = 0
(x-3)/(2*(x-3)) = 0 // * 2*(x-3)
x-3 = 0
x-3 = 0 // + 3
