You can put this solution on YOUR website!
x = dollar amount invested at 2.50%
y = dollar amount invested at 3.54%
---
x = y/2
2x - y = 0
0.025x + 0.0354y = 247
---
put the system of linear equations into standard form
---
2x - y = 0
0.025x + 0.0354y = 247
---
copy and paste the above standard form linear equations in to this solver:
