Maggie's brother is 3 years younger than twice her age the sum of their ages is 24. how old is Maggie?
Likurg_2 [28]

For this case, the first thing we must do is define variables.

We have then:

x: Maggie's age

y: Age of Maggie's brother

We write the system of equations that models the problem.

We have then:

y = 2x-3\\x + y = 24

We solve the system of equations.

For this, we use substitution:

x + (2x-3) = 24

From here, we clear the value of x:

3x - 3 = 24\\3x = 24 + 3\\3x = 27

x = \frac{27}{3}\\x = 9

Answer:

Maggie is 9 years old
