20x+5y=-15 solve for y

Okay, so we have 20x+5y=-15.

To find y, let's plug in 0 for x, that way we have 20(0)+5y=-15.

Now do 20(0) and we have the equation: 5y=-15

divide both sides by 5 and we get y=-3!
20x+5y = -15
Take the 20x to the other side to get.
5y = -20x -15
Then divide both sides by 5.
So y = -4x -3

I know someone else has answered with something else, but this is how I'd do it ;)
