x = 0
2*x-3 = 0
2*x-3 = 0
2*x-3 = 0 // + 3
2*x = 3 // : 2
x = 3/2
x in (-oo:0) U (0:3/2) U (3/2:+oo)
2/x = 4/(2*x-3) // - 4/(2*x-3)
2/x-(4/(2*x-3)) = 0
2/x-4*(2*x-3)^-1 = 0
2/x-4/(2*x-3) = 0
(-4*x)/(x*(2*x-3))+(2*(2*x-3))/(x*(2*x-3)) = 0
2*(2*x-3)-4*x = 0
-6 = 0
-6/(x*(2*x-3)) = 0
-6/(x*(2*x-3)) = 0 // * x*(2*x-3)
-6 = 0
-6 = 0
