Y + 2x = 4 How do I complete this?
Leviafan [203]
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.
