A person invested 7,000 dollars, she made $532 in profit, some of the money was invested in 8% simple interest and some was invested in 6% simple interest, how much was invested at each?

Ok thanks, here is one more...A person invested 7,000 dollars, she made $532 in profit, some of the money was invested in 8% simple interest and some was invested in 6% simple interest, how much was invested at each?

x = amount invested at 8%
7000 - x = amount invested at 6%

Interest earned in 1 year on x dollars invested at 8% is 0.08x
Interest earned in 1 year on (7000 - x) dollars invested at 6% is 0.06(7000 - x)

We know the total interest earned in 1 year is $532. So....

0.08x + 0.06(7000 - x) = 532

Can you take it from here?
