# Is the ordered pair (2,7) is a solution of the equation: y - x = 5?

May 6, 2016

Yes.

#### Explanation:

The ordered pair $\left(2 , 7\right)$ is in the form $\left(x , y\right)$ so
$x = 2$
$y = 7$

Substitute $x$ and $y$ values into the equation $y - x = 5$

$7 - 2 = 5$
$5 = 5$

Since the equation is correct, the ordered pair is a solution.
