You can put this solution on YOUR website!
x = dollars invested in A = 16000
y = dollars invested in B
---
10x + 3y = 7(x + y)
x = 16000
---
put the system of linear equations into standard form
---
10x + 3y = 7x + 7y
x = 16000
---
3x - 4y = 0
x = 16000
---
copy and paste the above standard form linear equations in to this solver:
