Solve for r K=9r-s

$K = 9 r - s$

Step 1

Rewrite the equation as $9 r - s = K$ .

$9 r - s = K$

Step 2

Add $s$ to both sides of the equation.

$9 r = K + s$

Step 3

Divide each term in $9 r = K + s$ by $9$ and simplify.

Divide each term in $9 r = K + s$ by $9$ .

$\frac{9 r}{9} = \frac{K}{9} + \frac{s}{9}$

Simplify the left side.

Cancel the common factor of $9$ .

Cancel the common factor.

$\frac{9 r}{9} = \frac{K}{9} + \frac{s}{9}$

Divide $r$ by $1$ .

$r = \frac{K}{9} + \frac{s}{9}$
