Question 926295: Marlon is now twice as old as Lenlen, Five years ago he was three times as old as Lenlen. Find their Present ages. Please heeeelp Answer by TimothyLamb(4379) (Show Source):
You can put this solution on YOUR website! x = mar age now
y = len age now
---
x = 2y
x - 5 = 3(y - 5)
---
put the system of linear equations into standard form
---
x - 2y = 0
x - 5 = 3(y - 5)
x - 5 = 3y - 15
x - 3y = -10
---
x - 2y = 0
x - 3y = -10
---
copy and paste the above standard form linear equations in to this solver:
