Okay so take away $20 from your $90 you get $70. Divide $70 by $5 per hour and you get to rent a surfboard for 14 hours.

An equation to solve that problem can be

5x+20=90. X represents the hour/s.

You'd first use the subtraction property of equality and subtract 20 from both sides to get 5x=70. Then, you use the division property of equality and divide both sides by 5 to isolate the variable. You'd then get x=14

You'd be able to rent the surfboard for 14 hours
