# If (-7, y) is a solution to the equation 2x-7y-4x=0, what is the value of y?

Mar 4, 2018

$y = 2$

#### Explanation:

Let's move terms based on the variable that it is with.

$2 x - 4 x = 7 y$

So we know that $x = - 7$.

$2 \left(- 7\right) - 4 \left(- 7\right) = 7 y$

Which is simplified to...

$- 14 + 28 = 7 y$
$14 = 7 y$

Divide both sides by $7$ to isolate and solve for $y$ and you should get $y = 2$.
