Answer:

6 years

Step-by-step 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

[tex]x+2x-5=13[/tex]

[tex]3x=13+5[/tex]

[tex]3x=18[/tex]

[tex]x=\frac{18}{3}=6[/tex]

Hence, Maggie's age=6 years
