add 15 to both sides
subtract 5 from both sides
subtract 15 from both sides

Explanation:

Step1: Isolate variable $m$

To solve $15 = m - 5$, we need to cancel the $-5$ on the right side. The inverse operation of subtraction is addition.

Step2: Apply inverse operation

Add 5 to both sides of the equation to keep it balanced:
$15 + 5 = m - 5 + 5$
