Question

solve for x.
$x - 15 = y$
$x = \square$

Explanation:

Step1: Isolate x by adding 15

Add 15 to both sides of the equation to cancel the -15 on the left.
$x - 15 + 15 = y + 15$

Step2: Simplify both sides

The -15 and +15 on the left cancel out, leaving x isolated.
$x = y + 15$

Answer:

$x = y + 15$
