$z = \frac{K}{x y}$

Step 1

Rewrite the equation as $\frac{K}{x y} = z$ .

$\frac{K}{x y} = z$

Step 2

Multiply both sides by $x y$ .

$\frac{K}{x y} (x y) = z (x y)$

Step 3.1.1.1

Cancel the common factor.

$\frac{K}{x y} (x y) = z (x y)$

Step 3.1.1.2

Rewrite the expression.

$K = z (x y)$

$K = z (x y)$

$K = z (x y)$
