Question

The ages of John and Martha together are 28 years. If John is 4 years older than Martha. What is Martha's age?

Answer 1

Let the variable x represent their respective age.

Explanation:

As John is 4 years older, that would be (4+x)

`4+x+x=28`

`2x=24`

`x=12`

Martha is 12 and John is 16 (`12+4=16`)
