Step 2.1

Apply the distributive property.

$8 - 2 p - 2 (- m) = m$

Step 2.2

Multiply $- 1$ by $- 2$ .

$8 - 2 p + 2 m = m$

Step 3

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

Step 3.1

Subtract $8$ from both sides of the equation.

$- 2 p + 2 m = m - 8$

Step 3.2

Subtract $2 m$ from both sides of the equation.

$- 2 p = m - 8 - 2 m$

Step 3.3

Subtract $2 m$ from $m$ .

$- 2 p = - m - 8$

Step 4

Divide each term in $- 2 p = - m - 8$ by $- 2$ and simplify.

Step 4.1

Divide each term in $- 2 p = - m - 8$ by $- 2$ .

$\frac{- 2 p}{- 2} = \frac{- m}{- 2} + \frac{- 8}{- 2}$

Step 4.2

Simplify the left side.

Step 4.2.1.1

Cancel the common factor.

$\frac{- 2 p}{- 2} = \frac{- m}{- 2} + \frac{- 8}{- 2}$

Step 4.2.1.2

Divide $p$ by $1$ .

$p = \frac{- m}{- 2} + \frac{- 8}{- 2}$

Step 4.3

Simplify the right side.

Step 4.3.1.1

Dividing two negative values results in a positive value.

$p = \frac{m}{2} + \frac{- 8}{- 2}$

Step 4.3.1.2

Divide $- 8$ by $- 2$ .

$p = \frac{m}{2} + 4$
