Question

Maggie's brother is 11 years younger than three times her age. The sum of their ages is 37.

How old is Maggie?
Maggie is_______years old.​

Answer 1

x: Maggie's age

3x-11: Maggie's brother's age

3x-11+x = 37

4x - 11 = 37

4x = 48

x = 12 Maggie's age

3(12)- 11= 36-11= 25 years old ( Maggie's brother's age)
