Answer:

[tex]-x\text{ + 2y = -4}[/tex]

Explanation:

Here, we want to write the given equation in standard form

The equation of a line in standard form is as follows:

[tex]Ax\text{ + By = C}[/tex]

What we have to do now is to bring the x and y terms together

We can have this as follows:

[tex]-x\text{ + 2y = -4}[/tex]

-4 - 2y = -x

We want to leave -4 alone on the left

That means we have to transfer -2y that is there with it

To transfer -2y over the equality sign , its sign changes

-4 = +2y - x

But +2y can be written as 2y only

Finally by re-arrangement:

-x + 2y = -4
