If you pay $525 for rent each month and you pay 35% of your monthly income for rent, what is your yearly income?

x-.35x+525

.65x=525

divide both sides by .65

x= 807.69

i then multiplied by 12 but didn't come close to answer -18,000

I have a basic math book with just basic definitions and problems, and I 've forgotten most of this stuff. If anyone knows of any good websites with detailed formulas and examples on how to solve math problems like this , it would be much appreciated.
