Question

five yrs ago, a mother was 5 times older than her son. in 8 yrs time, the mother will be 3times older than her son. how old are the mother and her son?

Answer 1

x years son age, y years mother age: y - 5 = 5(x - 5) and (y + 8) = 3(x + 8)

y = 5x - 20

y = 3x + 16

5x - 20 = 3x + 16; x = 18; y = 70
