Do you mean 2x105x\dfrac{2x-10}{5-x}, if so can you factorize the numerator?

Or did you really mean 2x - 10x or something else?

i mean 2x - (10x divided by 5 - x)

Right, so

2x10x5x\displaystyle 2x - \dfrac{10x}{5 - x}

In that case, you want to put everything over a denominator of 5 - x, so what can you do with the 2x?
