Question

Puede alguien simplificarla :

$x - \frac{2x - 8}{4}$

Answer 1

$x - \frac{2x - 8}{4} = \\ \\ x- \frac{2(x-4)}{4}= \\ \\ x- \frac{2(x-4)}{2*2} = \\ \\ x- \frac{\not{2}(x-4)}{\not{2}*2}= \\ \\ x- \frac{x-4}{2} = \\ \\ \frac{2x}{2}- \frac{x-4}{2}= \\ \\ \frac{2x-(x-4)}{2} = \\ \\ \frac{2x-x+4}{2} = \\ \\ \boxed{ \frac{x+4}{2} }$
