Maggies brother is 7 years younger than twice here. The sum of their ages i 32 How old is Maggie
Maggie is
Years old

Maggie is 13years old

Step-by-step explanation:

Let the age of Maggie be = x

Let her brothers age be = y

Given:

Brother is 7 years younger than twice her age , y = 2x - 7   ( 1 )

[ Twice her age = 2x

7 years younger than twice her age = 2x - 7 ]

Sum of their ages , x + y = 32 ( 2 )

Substitute ( 1 ) in ( 2 ) :

x + ( 2x - 7 ) = 32

x + 2x - 7 = 32

3x = 32 + 7

3x = 39

x = 13

Maggie's age  = 13 years

Substitute x in ( 1 ) :

y = 2x - 7

  = 2 ( 13 ) - 7

  = 26 - 7

  = 19

Brother's age = 19 years
