Answer 2

Answer:

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

Step-by-step 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!
