# How do you solve 5x+4 <39?

Jun 15, 2018

$x < 7$

#### Explanation:

In a inequality you can add and subtract however you want to.

$5 x + 4 < 39$
Minus $4$ both sides results in: $5 x < 35$

You can divide with a constant as long as its positive.

Dividing by $5$ on both sides results in: $x < 7$

Summary:
You can use a inequality just like a equation but you have to be very careful as sometimes you have to flip the inequality sign (if the operation you are applying is decreasing)
