# How do you solve and write the following in interval notation: x - 4 < 1?

Sep 13, 2017

See a solution process below:

#### Explanation:

Add $\textcolor{red}{4}$ to each side of the inequality to solve for $x$ while keeping the inequality balanced:

$x - 4 + \textcolor{red}{4} < 1 + \textcolor{red}{4}$

$x - 0 < 5$

$x < 5$

Or, in interval notation:

$\left(- \infty , 5\right)$
