Question

Answer 1

Answer:

Total age of a mother and her daughter is 60 years

x + y = 60

and the difference between their ages is 30 years,

x - y = 30

What is the age of the mother?

x + y = 60

x - y = 30

x = 60 - y

x = 30 + y

60 - y = 30 + y

2y = 30

y = 15

x = 60 - y = 60 - 15 = 45

Mother is 45 and daughter is 15
