Solve using substitution: y + 2x = -1 and y - 3x = 16

x= -1-y/2 AND x= -16-y/3

Step-by-step explanation:

1. Subtract y from both sides.

2. Divide both sides by the denominator.

When looking at the equation given, we can conclude that the y-intercept is -1, so we will start there, then we will do the rise over run method. We will go up 4 and over 1, and repeat.

When y = 1 we can use the graph we just made to find our answer. Go to where y = 1 and go to the line, then go down to find that x is equal to roughly .5.

Hope this helps!
