# How do you simplify 3.2 (x + y) + 2.3 (x+y) +4x?

Jun 3, 2018

$9.5 x + 5.5 y$

#### Explanation:

First, use the distributive property to simplify $3.2 \left(x + y\right)$ and $2.3 \left(x + y\right)$:
$3.2 x + 3.2 y + 2.3 x + 2.3 y + 4 x$

Now color-code the like terms:
$\textcolor{red}{3.2 x} \quad \textcolor{b l u e}{+ \quad 3.2 y} \quad \textcolor{red}{+ \quad 2.3 x} \quad \textcolor{b l u e}{+ \quad 2.3 y} \quad \textcolor{red}{+ \quad 4 x}$

Combine like terms:
$9.5 x + 5.5 y$

Hope this helps!
