Answer 2

Answer:$\frac{31}{6}$

Step-by-step explanation:

Given

$\Rightarrow \frac{12-3y}{2}+y\frac{2y-4}{y}$

$\Rightarrow \frac{12-3y}{2}+\frac{y^2+2y-4}{y}$

Now for $y=3$

$\Rightarrow \frac{12-3\times 3}{2}+\frac{3^2+2\times 3-4}{3}$

$\Rightarrow \frac{3}{2}+\frac{9+6-4}{3}$

$\Rightarrow \frac{3}{2}+\frac{11}{3}$

$\Rightarrow \frac{9+22}{6}=\frac{31}{6}$
