consider the following pair of equations:
y = x + 4
y = −2x − 2
explain how you will solve the pair of equations by substitution. show all the steps and write the solution in (x, y) form.

First thing to note is that both equations equal y, and therefore equal each other. Set this up as so:
x + 4 = - 2x - 2
Next, you will move all integers to one side, and variables to the other, also known as isolating.
Add 2 to both sides and subtract x from both sides. It will give you this:
6 = - 3x
Now divide both sides by - 3
- 2 = x

You may choose whichever equation you would like to plug x into. For a more simplistic way, choose the first one.

y = - 2 + 4
y = 2

With both x and y, you have your solution: (-2,2)
