m = Margaret's age
m + 4 = Kate's age
m + 7 = Margaret's age in 7 yrs
m + 4 + 7 = m + 11 = Kate's age in 7 yrs
m + 7 + m + 11 = 70
2m + 18 = 70
2m = 52
m = 26
Margaret is 26
Kate is 30
m + 4 = Kate's age
m + 7 = Margaret's age in 7 yrs
m + 4 + 7 = m + 11 = Kate's age in 7 yrs
m + 7 + m + 11 = 70
2m + 18 = 70
2m = 52
m = 26
Margaret is 26
Kate is 30
