Answer:
Levi is 53 yrs now
Step-by-step explanation:
sum = 76yrs
Levi = 3x -8
Monique = x - 8
8yrs ago
sum= 76 - 8 - 8( the two 8s are from each of the two brothers).
= 60yrs
Levi=3x
Monique=x
3x + x = 60
4x = 60
x = 15yrs
Levi = 3x
= 15 x 3
= 45 yrs(8yrs ago)
now = 45 + 8
= 53yrs now
Monique = x
= 15
now = 15 + 8
23yrs now
