$- 8 = 4 + \frac{y}{2}$

Step 1

Rewrite the equation as $4 + \frac{y}{2} = - 8$ .

$4 + \frac{y}{2} = - 8$

Step 2

Move all terms not containing $y$ to the right side of the equation.

Step 2.1

Subtract $4$ from both sides of the equation.

$\frac{y}{2} = - 8 - 4$

Step 2.2

Subtract $4$ from $- 8$ .

$\frac{y}{2} = - 12$

Step 3

Multiply both sides of the equation by $2$ .

$2 \frac{y}{2} = 2 \cdot - 12$

Step 4

Simplify both sides of the equation.
