Step 2.1

Add $\frac{2}{3}$ to both sides of the inequality.

$\frac{x}{2} > 3 + \frac{2}{3}$

Step 2.2

To write $3$ as a fraction with a common denominator, multiply by $\frac{3}{3}$ .

$\frac{x}{2} > 3 \cdot \frac{3}{3} + \frac{2}{3}$

Step 2.3

Combine $3$ and $\frac{3}{3}$ .

$\frac{x}{2} > \frac{3 \cdot 3}{3} + \frac{2}{3}$

Step 2.4

Combine the numerators over the common denominator.

$\frac{x}{2} > \frac{3 \cdot 3 + 2}{3}$

Step 2.5

Simplify the numerator.
