You can put this solution on YOUR website!
Total amount of money invested: $25000
x+y=25000,
Total yearly interest for the two accounts is: $1555
0.06*x+0.065*y=1555
x=25000-y
Substitute for x
0.06*(25000-y)+0.065*y=1555
Multiply out
1500-0.06y+0.065*y=1555
Combine like terms.
0.005*y=55
Isolate y
y=$11000.00 at 6.5%
x=25000-y
Calculate x
x=$14000.00 at 6%
Check
0.06*14000+0.065*11000=1555
840+715.0=1555
1555.0=1555
If this statement is TRUE and neither amount is negative then all is well
