Solve for r -6-2r-7=17+r

$- 6 - 2 r - 7 = 17 + r$

Subtract $7$ from $- 6$ .

$- 2 r - 13 = 17 + r$

Move all terms containing $r$ to the left side of the equation.

Subtract $r$ from both sides of the equation.

$- 2 r - 13 - r = 17$

Subtract $r$ from $- 2 r$ .

$- 3 r - 13 = 17$

Move all terms not containing $r$ to the right side of the equation.

Add $13$ to both sides of the equation.

$- 3 r = 17 + 13$

Add $17$ and $13$ .

$- 3 r = 30$

Divide each term in $- 3 r = 30$ by $- 3$ and simplify.

Divide each term in $- 3 r = 30$ by $- 3$ .

$\frac{- 3 r}{- 3} = \frac{30}{- 3}$

Simplify the left side.

Cancel the common factor of $- 3$ .

Cancel the common factor.

$\frac{- 3 r}{- 3} = \frac{30}{- 3}$

Divide $r$ by $1$ .

$r = \frac{30}{- 3}$

Simplify the right side.

Divide $30$ by $- 3$ .

$r = - 10$
