Move $- 3$ to the left of $y$ .

$3 + \frac{- 3 \cdot y}{2} = 0$

Move the negative in front of the fraction.

$3 - \frac{3 y}{2} = 0$

Step 3

Subtract $3$ from both sides of the equation.

$- \frac{3 y}{2} = - 3$

Step 4

Multiply both sides of the equation by $- \frac{2}{3}$ .

$- \frac{2}{3} (- \frac{3 y}{2}) = - \frac{2}{3} \cdot - 3$

Step 5

Simplify both sides of the equation.

Simplify the left side.

Simplify $- \frac{2}{3} (- \frac{3 y}{2})$ .

Cancel the common factor of $2$ .

Move the leading negative in $- \frac{2}{3}$ into the numerator.

$\frac{- 2}{3} (- \frac{3 y}{2}) = - \frac{2}{3} \cdot - 3$

Move the leading negative in $- \frac{3 y}{2}$ into the numerator.

$\frac{- 2}{3} \cdot \frac{- 3 y}{2} = - \frac{2}{3} \cdot - 3$

Factor $2$ out of $- 2$ .
