help people again I don't know this

Create an equation for this and solve for h, how many hours Gina can rent the surfboard for $90.
Your equation should look like:
5h + 20 = 90
Subtract 20 from both sides.
5h = 70
Divide both sides by 5.
h = 14
Gina can rent a surfboard for 14 hours if she has $90.
