Answer:

x = -2y - 9

Step-by-step explanation:

First isolate the variable by putting the x on a side by itself.

-4x=36+8y (8y becomes positive when it changes sides)

Then divide the entire equation by -4 to make the x stand alone.

x = -9 -2y

Some teachers prefer the variables at the beginning of the equations so it could also read

x = -2y - 9

Hello there!

Question:-

[tex]-4x-8y=36[/tex]

We need to find the value of x.

Solution:-

[tex]\sf \longmapsto-4x-8y=36[/tex]

Firstly, Add 8y to both sides :-

[tex]\sf \longmapsto \: - 4x - 8y+8y=36+8y[/tex]

On Simplification:-

As (-) and (+) equals to (-),It Will be 8y-8y.Answer would be 0.

[tex]\sf \longmapsto \: - 4x - 0 = 36 + 8y[/tex]

[tex]\sf \longmapsto \: - 4x = 8y + 36[/tex]

Then, Divide both sides by -4:-

[tex]\sf \longmapsto \: \dfrac{4x}{ - 4} = \dfrac{8y + 36}{ - 4} [/tex]

On Simplification:-

[tex]\sf \longmapsto \: x = - 2y - 9[/tex]

______________________________________

Henceforth the value of x is :-

[tex] \boxed{\tt \: x = - 2y - 9}[/tex]
