An equivalent expression to x-2y+3

Step-by-step explanation:

1. The first thing you should do is put it equal to 0:

2. You want to get y by itself so the next thing you do is subtract 3 to the other side because it is being added right now. It should look like this:

            -3    -3

3. Since x is also being added on the left side of the equation you want to get x to the other side so you do the opposite of addition (subtraction) and subract the x to the other side of the equation:

-x              -x

4. The next thing you want to do is get rid of that -2. Right now it is being multiplied by the y and the opposite of multiplication is division, so you are going to want to divide -2 by both sides of the equation.

5. The -2's cancel out and the right side of the equation cannot be simplified anymore which makes the new or equivalent equation:

what graph
