Question 926881: Cassidy is 3 times as old as Drew. In 8 years, Cassidy will only be twice as old as Drew. How old is Cassidy right now? Answer by TimothyLamb(4379) (Show Source):
You can put this solution on YOUR website! x = cassidy age
y = drew age
---
x = 3y
x + 8 = 2(y + 8)
---
put the system of linear equations into standard form
---
x - 3y = 0
x + 8 = 2y + 16
---
x - 3y = 0
x - 2y = 8
---
copy and paste the above standard form linear equations in to this solver:
