Write -3/4x-6 in standard form using integers

taurus [48]

Answer:

$3x+4y=-24$

Therefore, option C is correct.

Step-by-step explanation:

We have been given the equation:

$y=\frac{-3x}{4}-6[/$

We will take LCM 4 on right hand side of the above equation:

$y=\frac{-3x-24}{4}$

Now, we will multiply the 4 in denominator on right hand side to the y in left hand side pof the equation we get:

$4y=-3x-24$

After rearranging the terms we get:

$3x+4y=-24$

Therefore, option C is correct.
