Step 1.1

Subtract $2 x$ from both sides of the equation.

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

Step 1.2

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

$\frac{3 x}{2} - 2 x \cdot \frac{2}{2} - 3 = 0$

Step 1.3

Combine $- 2 x$ and $\frac{2}{2}$ .

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

Step 1.4

Combine the numerators over the common denominator.

$\frac{3 x - 2 x \cdot 2}{2} - 3 = 0$

Step 1.5.1.1.1

Factor $x$ out of $3 x$ .

$\frac{x \cdot 3 - 2 x \cdot 2}{2} - 3 = 0$

Step 1.5.1.1.2

Factor $x$ out of $- 2 x \cdot 2$ .

$\frac{x \cdot 3 + x (- 2 \cdot 2)}{2} - 3 = 0$

Step 1.5.1.1.3

Factor $x$ out of $x \cdot 3 + x (- 2 \cdot 2)$ .

$\frac{x (3 - 2 \cdot 2)}{2} - 3 = 0$

Step 1.5.1.2

Multiply $- 2$ by $2$ .

$\frac{x (3 - 4)}{2} - 3 = 0$

Step 1.5.1.3

Subtract $4$ from $3$ .

$\frac{x \cdot - 1}{2} - 3 = 0$

Step 1.5.2

Move $- 1$ to the left of $x$ .

$\frac{- 1 \cdot x}{2} - 3 = 0$

Step 1.5.3

Move the negative in front of the fraction.

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

Step 2

Add $3$ to both sides of the equation.

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

Step 3

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

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

Step 4

Simplify both sides of the equation.

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

Step 4.1.1.1.2

Factor $2$ out of $- 2$ .

$2 (- 1) \frac{- x}{2} = - 2 \cdot 3$

Step 4.1.1.1.3

Cancel the common factor.

$2 \cdot - 1 \frac{- x}{2} = - 2 \cdot 3$
