Question 397996
1) x+%2B+y+=+12000
(2) .06x+%2B+.09y+=+855 (after 1 year)
(2) 6x+%2B+9y+=+85500
Multiply both sides of (1) by 6, then
subtract (1) from (2)
(2) 6x+%2B+9y+=+85500
(1) -6x+-+6y+=+72000
3y+=+13500
y+=+4500
and, from (1),
x+%2B+4500+=+12000
x+=+7500
The 6% loan was for $7500, and
the 9% loan was for $4500
