Step 1.2.1

Factor $2$ out of $10$ .

$\frac{2 (- v)}{2 (5)} = 4$

Step 1.2.2

Cancel the common factor.

$\frac{2 (- v)}{2 \cdot 5} = 4$

Step 1.2.3

Rewrite the expression.

$\frac{- v}{5} = 4$

$\frac{- v}{5} = 4$

$\frac{- v}{5} = 4$

Step 2

Multiply both sides by $5$ .

$\frac{- v}{5} \cdot 5 = 4 \cdot 5$

Step 3.1.1.1

Cancel the common factor.

$\frac{- v}{5} \cdot 5 = 4 \cdot 5$

Step 3.1.1.2

Rewrite the expression.

$- v = 4 \cdot 5$

$- v = 4 \cdot 5$

$- v = 4 \cdot 5$

Step 3.2

Simplify the right side.

Step 3.2.1

Multiply $4$ by $5$ .

$- v = 20$

$- v = 20$

$- v = 20$

Step 4

Divide each term in $- v = 20$ by $- 1$ and simplify.

Step 4.2.1

Dividing two negative values results in a positive value.

$\frac{v}{1} = \frac{20}{- 1}$

Step 4.2.2

Divide $v$ by $1$ .

$v = \frac{20}{- 1}$

$v = \frac{20}{- 1}$

Step 4.3

Simplify the right side.

Step 4.3.1

Divide $20$ by $- 1$ .

$v = - 20$

$v = - 20$

$v = - 20$
