Question

Bonnie is four years older than Clyde.
Ten years ago she was twice his age.
How old is Bonnie?

Answer 1

Answer:

Bonnie's age is 18

Step-by-step 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
