Solve for c 9c-18c-11c=-20

$9 c - 18 c - 11 c = - 20$

Step 1

Simplify $9 c - 18 c - 11 c$ .

Subtract $18 c$ from $9 c$ .

$- 9 c - 11 c = - 20$

Subtract $11 c$ from $- 9 c$ .

$- 20 c = - 20$

Step 2

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

Divide each term in $- 20 c = - 20$ by $- 20$ .

$\frac{- 20 c}{- 20} = \frac{- 20}{- 20}$

Simplify the left side.

Cancel the common factor of $- 20$ .

Cancel the common factor.

$\frac{- 20 c}{- 20} = \frac{- 20}{- 20}$

Divide $c$ by $1$ .

$c = \frac{- 20}{- 20}$

Simplify the right side.

Divide $- 20$ by $- 20$ .

$c = 1$
