Maggie's brother is four years younger than twice her age the sum of their ages is 14 how old is Maggie?

Step-by-step explanation:

Let x = Maggie's age

2x - 4 = Maggie brother age

x + (2x-4) = 14

Add 4 to each side

x+2x = 18

Combine like terms

3x=18

Division property of equality

x=6

Input 6 as x in the equation

2 (6) - 4 = 12-4=8

Maggie's brother is 8 years old and Maggie is 6 years old
