Question 371147
let $x be invested at 5%
$y be invested @6%
..
interest = $575
..
x+y = 10000.....................1
..
The percentage value is not taken. however the interest is multiplied by 100.
the result is the same
5x+6y=575*100
5x+6y=57,500....................2
multiply equation 1 by -5
-5x-5y=-50,000
add this to (2)
y=7500
$7,500 invested  @ 6%
Balance $2500 @ 5%
