i think you wrote :D

$\displaystyle \displaystyle \frac {4}{x-5} - \frac {1}{5} = \frac {-5}{5x-25} $

$\displaystyle \displaystyle \frac {4}{x-5} - \frac {1}{5} = \frac {-5}{5(x-5)} $

so multiply all with 5(x-5)

$\displaystyle \displaystyle 20 - (x-5) = -5 $

$\displaystyle \displaystyle -x+25=-5 $

$\displaystyle \displaystyle x = 30 $
