Please help Maggie's brother is 3 years younger than twice her age. The sum of their ages is 30.

denpristay [2]

I’m not sure if this is correct but this is the way i would solve it.

first, make an equation with the given information

2x-3=30

Then, add three to both sides

2x=33

Finally, divide both sides by 2

x= 16.5

x represents the age of maggie so all you have to do is plug the solution into the equation to check your answer.

2(16.5)-3= 30
