Steven wants to buy a $565 bicycle. Steven has no money saved, but will be able to deposit $30 into a savings account when he receives his paycheck each Friday. However, before Steven can buy the bike, he must give his sister $65 that he owes her. For how many weeks will Steven need to deposit money into his savings account before he can pay back his sister and buy the bike?

So if x is the number of weeks he has to save, then the equation

30x - 65 = 565
is what we're looking for.  The -65 is the money he owes his sister and the 565 is what he needs in the end...understand?

Solve for x the same way you've done so far :)
