x + y= 260394 ------------------------1
3.70% x + 8.80% y = $22,611.73
Multiply by 100
3.7 x + 8.8 y = $2,261,173.00 --------2

Multiply (1) by -3.7
we get

-3.7 x -3.7 y = -963457.80

Add this to (2)

0 x 5.1 y = $1,297,715.20

divide by 5.1

y = $254,453.96 loan at 8.80%
Balance $5,940.04 loan at 3.70%
CHECK
$5,940.04 --------- 3.70% ------- $219.78
$254,453.96 ------- 8.80% ------- $22,391.95
Total ------- $22,611.73
