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.
