1. **State the problem:** Solve the equation $$\frac{6}{x+2} = \frac{5x-1}{2-3x}$$ for $x$.
2. **Understand the formula and rules:** To solve an equation with fractions, we can cross-multiply to eliminate the denominators, provided the denominators are not zero.
3. **Cross-multiply:**
$$6(2-3x) = (5x-1)(x+2)$$
4. **Expand both sides:**
$$12 - 18x = 5x^2 + 10x - x - 2$$
Simplify the right side:
$$12 - 18x = 5x^2 + 9x - 2$$
5. **Bring all terms to one side to set the equation to zero:**
$$0 = 5x^2 + 9x - 2 - 12 + 18x$$
Simplify:
$$0 = 5x^2 + 27x - 14$$
6. **Solve the quadratic equation:**
Use the quadratic formula:
$$x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$$
where $a=5$, $b=27$, and $c=-14$.
Calculate the discriminant:
$$\Delta = 27^2 - 4 \times 5 \times (-14) = 729 + 280 = 1009$$
7. **Find the roots:**
$$x = \frac{-27 \pm \sqrt{1009}}{10}$$
8. **Check for restrictions:**
Denominators cannot be zero:
- $x + 2 \neq 0 \Rightarrow x \neq -2$
- $2 - 3x \neq 0 \Rightarrow x \neq \frac{2}{3}$
Neither root equals these values, so both are valid.
**Final answer:**
$$x = \frac{-27 + \sqrt{1009}}{10} \quad \text{or} \quad x = \frac{-27 - \sqrt{1009}}{10}$$
