Step 3.1.1

Subtract $\frac{3 w}{2}$ from both sides of the equation.

$w - \frac{3 w}{2} = - 6$

Step 3.1.2

To write $w$ as a fraction with a common denominator, multiply by $\frac{2}{2}$ .

$w \cdot \frac{2}{2} - \frac{3 w}{2} = - 6$

Step 3.1.3

Combine $w$ and $\frac{2}{2}$ .

$\frac{w \cdot 2}{2} - \frac{3 w}{2} = - 6$

Step 3.1.4

Combine the numerators over the common denominator.

$\frac{w \cdot 2 - 3 w}{2} = - 6$

Step 3.1.5

Simplify the numerator.

$\frac{- w}{2} = - 6$

Step 3.1.6

Move the negative in front of the fraction.

$- \frac{w}{2} = - 6$

Step 3.2

Multiply both sides of the equation by $- 2$ .

$- 2 (- \frac{w}{2}) = - 2 \cdot - 6$
