Find Ralph's age now. Answer by TimothyLamb(4379) (Show Source):
You can put this solution on YOUR website! ---
x = ralph
y = sara
---
x = 3y
x + 6 = 2(y + 6)
---
put the system of linear equations into standard form
---
x - 3y = 0
x + 6 = 2y + 12
---
x - 3y = 0
x - 2y = 6
---
copy and paste the above standard form linear equations in to this solver:
