A local gym charge nonmembers $ 19 per hour to use the tennis courts. Members pay a yearly fee of $300 and $4 per hour for using the tennis courts. Write and solve an equation to find how many hours you must use the tennis courts to justify becoming a member.

Member pays 300 + 4 x
guest pays 19 x
when are they the same?
19 x = 4 x + 300
15 x = 300
You can take it from there I think.
