Solve for r k=5r-9s

$k = 5 r - 9 s$

Step 1

Rewrite the equation as $5 r - 9 s = k$ .

$5 r - 9 s = k$

Step 2

Add $9 s$ to both sides of the equation.

$5 r = k + 9 s$

Step 3

Divide each term in $5 r = k + 9 s$ by $5$ and simplify.

Divide each term in $5 r = k + 9 s$ by $5$ .

$\frac{5 r}{5} = \frac{k}{5} + \frac{9 s}{5}$

Simplify the left side.

Cancel the common factor of $5$ .

Cancel the common factor.

$\frac{5 r}{5} = \frac{k}{5} + \frac{9 s}{5}$

Divide $r$ by $1$ .

$r = \frac{k}{5} + \frac{9 s}{5}$
