$x = 12$

#### Explanation:

Because the denominators need to be the same number, so you multiply $\frac{x}{2}$ by $\frac{3}{3}$ and so it will equal

$\frac{3 x}{6} - \frac{x}{6} = 4$

Then, you subtract and it will equal

$\frac{2 x}{6} = 4$

Then, you follow PEMDAS and multiply $6$ on both sides to eliminate the divide by 6, so it would equal

$2 x = 24$

You divide by $2$ on both sides and $x$ will equal $12$.
