# The second of two numbers is 6 times the first. Their sum is 84. What are the numbers?

Nov 19, 2016

The numbers are $12$ and $72$.

#### Explanation:

Let the first number be $x$; the second number, therefore is $6 x$, and their sum is $84$. Hence:

$x + 6 x = 84$

$7 x = 84$

$x = \frac{84}{7}$

$x = 12$

and

$6 x = 72$
