Question

Given: After 8 years, Alia will be four times as old as she was 4 years ago.
To find: Alia's present age.​

Answer 1

Step-by-step explanation:

Let Alia's present age be x years.

Therefore Alia's age after 8 years = x+8 years

Also, her age 4 years ago = x+4 years

According to the question,

x+8 = (x-4) 4

x+8 = 4x-16

x-4x = -16-8

x = 8

Hence, Alia's present age is 8 years.
