Solve for p -10p+9p=12

$- 10 p + 9 p = 12$

Step 1

Add $- 10 p$ and $9 p$ .

$- p = 12$

Step 2

Divide each term in $- p = 12$ by $- 1$ and simplify.

Divide each term in $- p = 12$ by $- 1$ .

$\frac{- p}{- 1} = \frac{12}{- 1}$

Simplify the left side.

Dividing two negative values results in a positive value.

$\frac{p}{1} = \frac{12}{- 1}$

Divide $p$ by $1$ .

$p = \frac{12}{- 1}$

Simplify the right side.

Divide $12$ by $- 1$ .

$p = - 12$
