Conner Mclean · Answer 1

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; )

Ariel Pratt · Answer 2

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!
