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=-15divide both sides by 5 and we get y=-3!
20x+5y = -15Take the 20x to the other side to get.5y = -20x -15Then divide both sides by 5.So y = -4x -3I know someone else has answered with something else, but this is how I'd do it ;)
