# How do you solve sqrt(x+3) =10?

Jun 10, 2016

$x = 97$

#### Explanation:

Let us first remove the square root, on the left side.

To do this, find the square of both sides of the equation:

${\left(\sqrt{x + 3}\right)}^{2} = {10}^{2}$

$x + 3 = 100$

$x + 3 \textcolor{red}{- 3} = 100 \textcolor{red}{- 3}$

$x = 97$
