Question

A mother is 24years older than her daughter. Befor eight years she was seven times her her daughter's age. Find their present age.​

Answer 1

Answer:

Mother = 36 years old

Daughter = 12 years old

Step-by-step explanation:

Mother's age = M

Daughter's age = D

M = D + 24 -> Eq.1

M - 8 = 7(D -8)

M = 7D -56 + 8

M = 7D - 48 -> Eq.2

Equating both M:

D + 24 = 7D - 48

6D = 72

D = 12

M = 12 + 24

M = 36

Answer 2

x-8=(x+16)7

6x=-120

x=-20

so x+24

x=4
