maggie's brother is 7 years younger than three times her age. the sum of their ages is 41. how old is maggie?

x is equal to 12

Step-by-step explanation:

let maggie's age be x and her brother's, y

3x-7=y ~eqn 1

x+y=41 ~eqn 2

put equation 1into equation 2

x+y=41

x + 3x-7=41

4x=41+7

4x=48

x=48/4

x = 12
