# Help with Multi-step equations ?

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

I would like to say that I am completely confused by this and I have no idea how to do it, but I know how to do a multi step equation.

I really would like the help.

First: If Maggie is m, then her brother can be expressed as 2m-3.

Second: "The sum of their ages is 24". So 2m-3 + m = 24

Third: Solve for m: 3m = 27; m=9

Maggie is 9 years old.

Hope that helps.
