A woman has a total of $9,000 to invest. She invests part of the money in an account that pays 5% per year and the rest in an account that pays 12% per year. If the interest earned in the first year is $730, how much did she invest in each account?

F*.05+(9000F).12=730
solve for F, the amount of money invested at five percent. then 9000F is the amount at 12 percetn.
