Solve for c a=-bcd

$a = - b c d$

Rewrite the equation as $- b c d = a$ .

$- b c d = a$

Divide each term in $- b c d = a$ by $- 1 b d$ and simplify.

Divide each term in $- b c d = a$ by $- 1 b d$ .

$\frac{- b c d}{- 1 b d} = \frac{a}{- 1 b d}$

Simplify the left side.

Dividing two negative values results in a positive value.

$\frac{b c d}{b d} = \frac{a}{- 1 b d}$

Cancel the common factor of $b$ .

Cancel the common factor.

$\frac{b c d}{b d} = \frac{a}{- 1 b d}$

Rewrite the expression.

$\frac{c d}{d} = \frac{a}{- 1 b d}$

Cancel the common factor of $d$ .

Cancel the common factor.

$\frac{c d}{d} = \frac{a}{- 1 b d}$

Divide $c$ by $1$ .

$c = \frac{a}{- 1 b d}$

Simplify the right side.

Move the negative in front of the fraction.

$c = - \frac{a}{b d}$
