**What is unknown?**

Value of the variable

**Reasoning:**

In an equation values of left-hand side (LHS) and right-hand side (RHS) are equal. The two sides of the equation are balanced. We perform mathematical operations so that the balance is not disturbed.

**Steps:**

By multiplying with \(\begin{align}\frac{3}{2}\end{align}\) in both sides,

\[\frac{3}{2} \times \frac{{2x}}{3}\,\, = \,\,18 \times \frac{3}{2}\]

We get \(x = 27\)
