Answer 1

use three variables:

x + y + z = 6486

so you will need three equations:

x = 5y (1st bank has 5 times as much as second bank)

z = 0.15(y+z) ( 3rd bank has 15% of total of bank 1 and 2 deposits)


Solve the system... set-up is the hard part.

Hope this helps.

Answer 2

Ooops... third equation is...

z = 0.15(x+y)

solve{x+y+z=6486, x=5y, z=.15(x+y)}


Sure has $846
