Question

Maggie's brother is 5 years younger than twice her age. The sum of their ages is 13. How old is Maggie?

Answer 1

Maggie is 9 years old. 9 minus 5 is 4 and 9 plus 4 is 13.

Answer 2

6 years

Explanation:

We are given that Maggie's brother is 5 years younger than twice her age.

Sum of their ages=13

We have to find the age of old Maggie.

Let Maggie's age =x years

Maggie's brother age=2x-5

Sum of ages=13

`x+2x-5=13`

`3x=13+5`

`3x=18`

`x=(18)/(3)=6`

Hence, Maggie's age=6 years
