$y=\frac{-x-3}{-2}$

Step-by-step explanation:

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

x-2y+3=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:

x-2y+3=0

-3 -3

x-2y=-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-2y=-3

-x -x

-2y=-x-3

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.

$\frac{-2y}{-2} =\frac{-x-3}{-2}$

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

$y=\frac{-x-3}{-2}$
