# Jack is 5 years younger than Mary. The sum of their ages is 37. If m represents Mary's age, which equation could be used to find m?

Dec 13, 2016

$m + \left(m - 5\right) = 37$

#### Explanation:

Mary's age is represented by $m$.

Since Jack is $5$ years younger than Mary, his age can be represented as $\left(m - 5\right)$.

Since we know that the sum of their ages is $37$, we can write:

$m + \left(m - 5\right) = 37$
