Hi there!

In order to solve this equation, we need to multiply:

Hi there! Hopefully this helps!

-----------------------------------------------------------------------------------------------------------

Answer to solving for y: <em> y = -2.</em>

<em />

Answer for simplifying the expression: -12y - 4.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

We are given that x = -4y and that the equation is 3x + 2y = 20.

<em>We need to evaluate.</em>

<em />

3x + 2y = 20

||

\/

3(-4y) + 2y = 20.

<em>To solve for y, y = -2.</em>
