Answer:

17.2

Step-by-step explanation:

3x=12+y

x=12+y/3

[tex]8( \frac{12 + y}{3}) \div 2y[/tex]

[tex] \frac{96 + 8y}{3} \times \frac{1}{2y} [/tex]

[tex] \frac{96 + 8y}{6y} [/tex]

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

[tex] \frac{96 + 8}{6} [/tex]

[tex] \frac{104}{6} [/tex]

[tex]17.2[/tex]
