Question

Maggie's brother is 13 years younger than twice her age. The sum of their ages is 32.

How old is Maggie?

Maggie is years old.

Answer 1

Explanation:

let Maggie's age be "m" and her brother's "p"

p= 2m-13 ~equation 1

p+m=32 ~ eqn 2

put eqn 1 into eqn 2

2m-13+m=32

3m=32+13

3m=45

m=45/3

m=15
