Question 581261: I figured it out:
654 = x + 9%x
(convert 9% to 1/11)
654 = x + 1/11x
11 x 654 = x + 11x
7194 = 12x
599.5 = x

You can put this solution on YOUR website!
9%=0.09=9%2F100=99%2F1100
1%2F11=100%2F1100
9% and 1%2F11 are close but not exactly the same number.
Fractions are overrated; stick with decimals if you can.
If $654 is the balance of $x invested at 9% simple interest for a year,
654=x%2B0.09x=%281%2B0.09%29x=1.09x --> x=654%2F1.09 --> highlight%28x=600%29
