<h2>
Explanation:</h2>
Here we have the following expression:

So we need to extend this. Remember that the difference of squares tells us:

So here:

Thus:

To solve this, what you will need to do is find the solution of one variable and then substitute it and solve for the other.
Here’s how to solve:
y+2x=4
-2x -2x
y=4-2x
4-2x + 2x =4
4=4
So if you’re trying to see if it is true, then your answer is that it’s true.
If you’re trying to find the linear equation, then your answer is y=-2x+4.
