Question 474459
Four years ago,Clara was 6 times as old as Mara. Four years from now, Clara will only be twice as old as Mara. How old are Mara and Clara this time?
-------------------
Equations:
(c-4) = 6(m-6)
(c+4) = 2(m+4)
------
Rearrange:
c - 6m = -32
c - 2m = 4
----
Subtract and solve for m:
4m = 36
m = 9 yrs (Mara's age now)
----
Solve for "c"
c = 2m+4
c = 2*9+4
c  22 yrs (Clara's age now)
