m-3 = 0 // + 3
m = 3
m in (-oo:3) U (3:+oo)
(2*m)/(m-3) = 6/(m-3)+4 // - 6/(m-3)+4
(2*m)/(m-3)-(6/(m-3))-4 = 0
(2*m)/(m-3)-6*(m-3)^-1-4 = 0
(2*m)/(m-3)-6/(m-3)-4 = 0
(2*m)/(m-3)-6/(m-3)+(-4*(m-3))/(m-3) = 0
2*m-4*(m-3)-6 = 0
2*m-4*m-6+12 = 0
6-2*m = 0
(6-2*m)/(m-3) = 0
(6-2*m)/(m-3) = 0 // * m-3
6-2*m = 0
