# How do you simplify 3x + 5x + 4?

May 29, 2018

$8 x + 4$

#### Explanation:

Given: $3 x + 5 x + 4$

Add terms that are alike, eg. $2 a + 3 a = 5 a$. $3 x$ and $5 x$ are alike:

$3 x + 5 x + 4 = 8 x + 4$

You could also factor the greatest common factor (GCF):

$8 x + 4 = 4 \left(2 x + 1\right)$
