Solve for y -9y=20+y

$- 9 y = 20 + y$

Step 1

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

Subtract $y$ from both sides of the equation.

$- 9 y - y = 20$

Subtract $y$ from $- 9 y$ .

$- 10 y = 20$

Step 2

Divide each term in $- 10 y = 20$ by $- 10$ and simplify.

Divide each term in $- 10 y = 20$ by $- 10$ .

$\frac{- 10 y}{- 10} = \frac{20}{- 10}$

Simplify the left side.

Cancel the common factor of $- 10$ .

Cancel the common factor.

$\frac{- 10 y}{- 10} = \frac{20}{- 10}$

Divide $y$ by $1$ .

$y = \frac{20}{- 10}$

Simplify the right side.

Divide $20$ by $- 10$ .

$y = - 2$
