The first step in solving an equation is to determine the variable/unknown. In this case, it is the #of months you can use the gym. You know that the amount of money you have to spend is 150 so the equation must be equal to that number. If you call the unknown/#of months

*x*, the equation would look like this:x=# of months

22+16×=150. Solve for x

-22. -22. Subtract 22 from both sides

16×=128. Divide by 16

×=8

The unknown is 8 months.

I hope this helps!

Let N be the number of months he pays for

Then amount payable = 22 + 16xN

The total money he has =150

So 22 + 16xN =150

16 N= 150- 22

16N = 128

N = 128/16 = Number of months he can use the club
