# How do you simplify 5(x+3)?

Mar 5, 2018

$5 x + 15$

#### Explanation:

$5 \left(x + 3\right)$ means $5 \cdot \left(x + 3\right)$
It also means $\left(5 \cdot 3\right) + \left(5 \cdot x\right)$
Solve $\left(5 \cdot 3\right)$
15
solve $\left(5 \cdot x\right)$
Because the value of $x$ is unknown, write it like $5 x$
add $15$ to $5 x$
$5 x + 15$
