Question #77dfc

Jan 9, 2018

$x = 5$
$y = 40$

Explanation:

We know both equations are equal to $y$ right, so we will set both equations equal to each other.

$y = y$

So

$8 x = 5 x + 15$

$8 x - 5 x = 15$

$3 x = 15$

$x = \frac{15}{3}$

$x = 5$

And since

$y = 8 x$

you have

$y = 8 \cdot 5 = 40$

There you have it.
