# How do you multiply 1/2 (2n - 4) - 2n?

Jul 30, 2016

use order of operations here by multiplying $\left(2 n - 4\right)$ by $\frac{1}{2}$ which gives you $\left(\frac{2 n}{2} - \frac{4}{2}\right)$. when you do the division, you are left with $n - 2$. remove the brackets and group like terms:
$n - 2 - 2 n$
$x = - n - 2$
