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}
