X-2/x-3 + x-4/x-3 = 10/3
2x-6/x-3 = 10/3
3(2x-6) = 10(x-3) [cross multiplication]
6x-18 = 10x-30
-18+30 = 10x-6x [transporting like terms with signs changed]
12 = 4x
12/4 = x
3 = x
but x=3 cannot be a solution
because the point is not defined since,
the value approaches infinity...
therefore, the answer is not defined.
