Question

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

Answer 1

Answer:

17.2

Step-by-step explanation:

3x=12+y

x=12+y/3

$8( \frac{12 + y}{3}) \div 2y$

$\frac{96 + 8y}{3} \times \frac{1}{2y}$

$\frac{96 + 8y}{6y}$

(y is divided by y so it no longer exists)

$\frac{96 + 8}{6}$

$\frac{104}{6}$

$17.2$
