Solve for c a=c/(2b)

$a = \frac{c}{2 b}$

Rewrite the equation as $\frac{c}{2 b} = a$ .

$\frac{c}{2 b} = a$

Multiply both sides by $2 b$ .

$\frac{c}{2 b} (2 b) = a (2 b)$

Simplify.

Simplify the left side.

Simplify $\frac{c}{2 b} (2 b)$ .

Rewrite using the commutative property of multiplication.

$2 \frac{c}{2 b} b = a (2 b)$

Cancel the common factor of $2$ .

Factor $2$ out of $2 b$ .

$2 \frac{c}{2 (b)} b = a (2 b)$

Cancel the common factor.

$2 \frac{c}{2 b} b = a (2 b)$

Rewrite the expression.

$\frac{c}{b} b = a (2 b)$

Cancel the common factor of $b$ .

Cancel the common factor.

$\frac{c}{b} b = a (2 b)$

Rewrite the expression.

$c = a (2 b)$

Simplify the right side.

Rewrite using the commutative property of multiplication.

$c = 2 a b$
