Bert is 5 years older than twice the age of mario. Nine years ago, the sum of their ages is 50. How old is each now?
Answered by Reiny
present:
Mario's age --- x
Bert's age ----- 2x+5

Nine years ago:
Mario --- x-9
Bert ---- (2x+5) - 9 = 2x -4

"Nine years ago, the sum of their ages is 50. "
----> x-9 + 2x-4 = 50
3x = 63
x = 21

Mario is now 21 and Bert is now 47

check:
9 yrs ago Mario was 12 and Bert was38
Is 12+38 = 50?
YES, all is good!
