Maggie's brother is 3 years younger than twice her age. The sum of their age is 24. How old is Maggie?

m + (2m - 3) = 24

3m - 3 = 24

3m = 27

m = 9

how did you get two 3's?

To determine Maggie's age, we need to set up equations based on the given information. Let's assume Maggie's age is "M" years.

According to the problem, Maggie's brother is 3 years younger than twice her age. So, Maggie's brother's age would be 2M - 3.

The sum of Maggie's and her brother's age is 24. Therefore, we can write the equation as:

M + (2M - 3) = 24

Simplifying the equation:

3M - 3 = 24

Adding 3 to both sides of the equation:

3M = 24 + 3

3M = 27

Dividing both sides of the equation by 3:

M = 27 / 3

M = 9

Therefore, Maggie is 9 years old.

m*2m is 3m
