# Thread: Simplifying the following expressions *Absolute values *

1. ## Simplifying the following expressions *Absolute values *

Hey guys, im having trouble with this question so please explain how to do it and show working if you could (:

Simplify the following expressions:

{ l 1-x l } / { 1 - x }

Thanks a lot (:

2. Use:

$\left |{1-x}\right |=\begin{Bmatrix} 1-x & \mbox{ if }& x\leq 1\\x-1& \mbox{if}& x>1\end{matrix}$
