Question

Bonnie is four years older than Clyde.

Ten years ago she was twice his age.
How old is Bonnie?

Answer 1

Bonnie's age is 18

Explanation:

Let

x ----> Bonnie's age

y ---> Clyde's age

we know that

`x=y+4` ----> equation A

`x-10=2(y-10)`

`x-10=2y-20`

`x=2y-20+10`

`x=2y-10` ----> equation B

substitute equation A in equation B

`y+4=2y-10`

Solve for y

`2y-y=4+10`

`y=14`

Find the value of x

`x=14+4=18`

therefore

Bonnie's age is 18

Clyde's age is 14
