$x = 20$ $x = 20$

Explanation:

You can perform an operation on both sides of an equation in order to preserve the validity of the equation and simplify it. Here's how you do it for yours:

$x - 7 = 13$ $x - 7 = 13$

$x - 7 + 7 = 13 + 7$ $x - 7 + 7 = 13 + 7$

$x + 0 = 20$ $x + 0 = 20$

$x = 20$ $x = 20$
