You can put this solution on YOUR website!
x = dollar amount in account a
y = dollar amount in account b
---
x + y = 10000
x/y = 4/5
5x = 4y
---
put the system of linear equations into standard form
---
x + y = 10000
5x = 4y
---
x + y = 10000
5x - 4y = 0
---
copy and paste the above standard form linear equations in to this solver:
