-50/x = 24/(x-3) // - 24/(x-3)
-(24/(x-3))-50/x = 0
-24*(x-3)^-1-50/x = 0
-24/(x-3)-50/x = 0
(-24*x)/(x*(x-3))+(-50*(x-3))/(x*(x-3)) = 0
-50*(x-3)-24*x = 0
150-74*x = 0
(150-74*x)/(x*(x-3)) = 0
(150-74*x)/(x*(x-3)) = 0 // * x*(x-3)
150-74*x = 0
150-74*x = 0 // - 150
-74*x = -150 // : -74
x = -150/(-74)
x = 75/37
x = 75/37
