Solve for r 4r+4r-16r-r-10r=19

$4 r + 4 r - 16 r - r - 10 r = 19$

Simplify $4 r + 4 r - 16 r - r - 10 r$ .

Add $4 r$ and $4 r$ .

$8 r - 16 r - r - 10 r = 19$

Subtract $16 r$ from $8 r$ .

$- 8 r - r - 10 r = 19$

Subtract $r$ from $- 8 r$ .

$- 9 r - 10 r = 19$

Subtract $10 r$ from $- 9 r$ .

$- 19 r = 19$

Divide each term in $- 19 r = 19$ by $- 19$ and simplify.

Divide each term in $- 19 r = 19$ by $- 19$ .

$\frac{- 19 r}{- 19} = \frac{19}{- 19}$

Simplify the left side.

Cancel the common factor of $- 19$ .

Cancel the common factor.

$\frac{- 19 r}{- 19} = \frac{19}{- 19}$

Divide $r$ by $1$ .

$r = \frac{19}{- 19}$

Simplify the right side.

Divide $19$ by $- 19$ .

$r = - 1$
