Question

Judy is now twice as old as adam, but 6 years ago, she was 5 times as old as he was. How old is judy now?

Answer 1

Answer:

Judy's age = 16

Adam's age = 8

Step-by-step explanation:

let Judy's age be x

Adam's age be y

present age

x = 2y equ (1)

before 6 years

x - 6 = 5(y - 6)

x - 6 = 5y - 30

x - 5y = - 24 equ (2)

substitute x in equ (2)

2y - 5y = - 24

- 3y = - 24

y = 24/3

y = 8

x = 2y

x = 2 × 8

x = 16

Answer 2

Judy is 16.

I put the answer in and it was right.
