Solve for y 9=5-y/3

$9 = 5 - \frac{y}{3}$

Rewrite the equation as $5 - \frac{y}{3} = 9$ .

$5 - \frac{y}{3} = 9$

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

Subtract $5$ from both sides of the equation.

$- \frac{y}{3} = 9 - 5$

Subtract $5$ from $9$ .

$- \frac{y}{3} = 4$

Multiply both sides of the equation by $- 3$ .

$- 3 (- \frac{y}{3}) = - 3 \cdot 4$

Simplify both sides of the equation.

Simplify the left side.

Simplify $- 3 (- \frac{y}{3})$ .

Cancel the common factor of $3$ .

Move the leading negative in $- \frac{y}{3}$ into the numerator.

$- 3 \frac{- y}{3} = - 3 \cdot 4$

Factor $3$ out of $- 3$ .

$3 (- 1) \frac{- y}{3} = - 3 \cdot 4$

Cancel the common factor.

$3 \cdot - 1 \frac{- y}{3} = - 3 \cdot 4$

Rewrite the expression.

$- - y = - 3 \cdot 4$

Multiply.

Multiply $- 1$ by $- 1$ .

$1 y = - 3 \cdot 4$

Multiply $y$ by $1$ .

$y = - 3 \cdot 4$

Simplify the right side.

Multiply $- 3$ by $4$ .

$y = - 12$
