You can put this solution on YOUR website! three years ago, jeffrey was twice as old as michael is now.
---
Equations:
j-3 = 2(m-3)
------
In nine years, jeffrey will be four times as old as michael is now.
j+9 = 4m
-----
Rearrange the equations:
j= 4m-9
j = 2m-3
---------
Solve using substitution:
4m-9 = 2m -3
2m = 6
m = 3 (michael's age now)
-------
Solve for "j":
j = 2m-3
j = 2*3-3
j = 3
what are jeffrey"s and michael's current ages?
They are both 3 yrs old.
Cheers,
Stan H.
