# How do you combine like terms in 3+ 2s - 4+3s?

Jan 3, 2017

First, group the like terms and then combine. See below for the full explanation.

#### Explanation:

First, group the like terms:

$\textcolor{b l u e}{3} + \textcolor{red}{2 s} - \textcolor{b l u e}{4} + \textcolor{red}{3 s} \to$

$\textcolor{b l u e}{3} - \textcolor{b l u e}{4} + \textcolor{red}{2 s} + \textcolor{red}{3 s}$

Now, we can combine like terms, the constants and the $s$ terms:

$\textcolor{b l u e}{\left(3 - 4\right)} + \textcolor{red}{\left(2 + 3\right) s}$

$\textcolor{b l u e}{- 1} + \textcolor{red}{5 s}$

or

$\textcolor{red}{5 s} - \textcolor{b l u e}{1}$
