$7 - \frac{y}{2} = 0$

Step 1

Subtract $7$ from both sides of the equation.

$- \frac{y}{2} = - 7$

Step 2

Multiply both sides of the equation by $- 2$ .

$- 2 (- \frac{y}{2}) = - 2 \cdot - 7$

Step 3

Simplify both sides of the equation.

Step 3.1.1.1.1

Move the leading negative in $- \frac{y}{2}$ into the numerator.

$- 2 \frac{- y}{2} = - 2 \cdot - 7$

Step 3.1.1.1.2

Factor $2$ out of $- 2$ .

$2 (- 1) \frac{- y}{2} = - 2 \cdot - 7$

Step 3.1.1.1.3

Cancel the common factor.

$2 \cdot - 1 \frac{- y}{2} = - 2 \cdot - 7$

Step 3.1.1.1.4

Rewrite the expression.

$- - y = - 2 \cdot - 7$

$- - y = - 2 \cdot - 7$

Step 3.1.1.2

Multiply.

Step 3.1.1.2.1

Multiply $- 1$ by $- 1$ .

$1 y = - 2 \cdot - 7$

Step 3.1.1.2.2

Multiply $y$ by $1$ .

$y = - 2 \cdot - 7$

$y = - 2 \cdot - 7$

$y = - 2 \cdot - 7$

$y = - 2 \cdot - 7$
