solve for a.

a - 18 = b

a =

Explanation:

Step1: Isolate $a$ by adding 18

Add 18 to both sides of the equation to cancel the -18 on the left.
$a - 18 + 18 = b + 18$

Step2: Simplify both sides

The left side simplifies to $a$, and the right side remains as $b+18$.
$a = b + 18$

Answer:

$a = b + 18$
