Let x = the amount invested at 7% (= 0.07) and ($15,000 - x) the amount invested at 6.5% (= 0.065). Change the percents to decimals and then set up your equation. Solve for x:
Simplify and solve for x.
Subtract 975 from both sides.
Divide both sides by 0.005

The amount invested ay 7% is $9,000
The amount invested at 6.5% is ($15,000 - $9,000) = $6,000
