Answer

$\boxed{y = \frac{24}{7}}$

Steps

Step 1 ：First, we need to simplify the equation and solve for y.

Step 2 ：$2y + \frac{4(y+3)}{5} - 12 = 0$

Step 3 ：$\frac{10y + 4(y+3) - 60}{5} = 0$

Step 4 ：$10y + 4(y+3) - 60 = 0$

Step 5 ：$10y + 4y + 12 - 60 = 0$

Step 6 ：$14y - 48 = 0$

Step 7 ：$14y = 48$

Step 8 ：$y = \frac{48}{14}$

Step 9 ：$\boxed{y = \frac{24}{7}}$
