Solve: `(x^2-4x+7)/(x^2-7x+12)lt=2/3` .

Explanation

To solve the inequality \(\frac{x^2 - 4x + 7}{x^2 - 7x + 12} \leq \frac{2}{3}\), we will follow these steps:

### Step 1: Rearrange the inequality
We start by moving \(\frac{2}{3}\) to the left side of the inequality:
\[ \frac{x^2 - 4x + 7}{x^2 - 7x + 12} - \frac{2}{3} \leq 0 \]
