You can put this solution on YOUR website!
x = Cara's age now
y = Chuck's age now
---
x = y + 8
x + 5 = 2(y + 5)
---
x = y + 8
x + 5 = 2y + 10
---
x = y + 8
x - 2y = 5
---
put the system of linear equations into standard form
---
x - y = 8
x - 2y = 5
---
copy and paste the above standard form linear equations in to this solver:
