Question 970135
In twelve years time, the combined age of my four nieces will be 94.
 What will it be in 5 years time?
:
let n = your nieces present age
"In twelve years time, the combined age of my four nieces will be 94."
4(n+12) = 94
4n + 48 = 94
4n = 94 - 48
4n = 46
n = 46/4
n = 11{{{1/4}}} present age
:
What will it be in 5 years time?
4(11{{{1/4}}} + 5) = 
4(16{{{1/4}}}) = 66 is their combined age in 5 yrs
