# How do you simplify  19x + 18y + 5 + 18x - 8y - 17?

Mar 2, 2018

$37 x + 10 y - 12$

#### Explanation:

$\text{simplify by collecting like terms}$

$\textcolor{red}{19 x} \textcolor{b l u e}{+ 18 y} \textcolor{m a \ge n t a}{+ 5} \textcolor{red}{+ 18 x} \textcolor{b l u e}{- 8 y} \textcolor{m a \ge n t a}{- 17}$

$= \left(\textcolor{red}{19 x + 18 x}\right) + \left(\textcolor{b l u e}{18 y - 8 y}\right) + \left(\textcolor{m a \ge n t a}{5 - 17}\right)$

$= \textcolor{red}{37 x} \textcolor{b l u e}{+ 10 y} \textcolor{m a \ge n t a}{- 12}$
