Question 476920
Maria is 6yrs older than John, 
John is twice as old as Michael? 
If all their ages are added together it could be 102 
how old is maria
-----------------------
Equations:
m = j + 6
j = 2k
m + j + k = 102
----
Substitute and solve for "j":
j+6 + j + j/2 = 102
---
(5/2)j = 96
j = (2/5)*96
j = 38.4
---
Maria = j+6 = 44.4 yrs old
