18-4=14

14+6=20

Answer 2

`\huge\boxed{\text{Maggie = 6 years, Brother = 21 years}}`

Explanation:

We can create two equations based on the word problems, where
`m` is Maggie's age and
`b` is her brother's age.

`m + b = 27`

`b = 4m - 3`

We can now substitute
`4m-3` in as
`b` into
`m+b=27`.

`m + (4m-3) = 27\\\\5m - 3 = 27\\\\5m = 30\\\\m = 6`

Now that we know the value of
`m`, we can substitute it into
`m+b=27`.

`6 + b = 27\\\\b = 27-6\\\\b = 21`

Hope this helped!
