If 3x−y=12, what is the value of <br> 8x<br> 2y<br> ?

anygoal [31]

If 3x-y=12, what is the value of 8x/2y?

Answer:

$\frac{8x}{2y} =\frac{4x}{3x-12}$

Step-by-step explanation:

$3x-y=12$

$-y=12-3x$

$y=3x-12$ -------------------------(equation 1)

Now,

$\frac{8x}{2y} =\frac{8x}{2(3x-12)}$ ---------(from equation 1)

$=\frac{8x}{6x-24}$

$=\frac{8x}{2(3x-12)}$

$=\frac{4x}{3x-12}$

Therefore, the value of $\frac{8x}{2y} =\frac{4x}{3x-12}$
