Problema Solution
Mio is 22 years older than Yui. Seven years ago the sum of their ages was 32. How old are they now?
Answer provided by our tutors
let
m = the age of Mio now
y = the age of Yui now
Mio is 22 years older than Yui
m = 22 + y
Seven years ago the sum of their ages was 32
m - 7 + y - 7 = 32
m + y = 46
by solving the system of equations
m = 22 + y
m + y = 46
we find
m = 34 years
y = 12 years
