1. **State the problem:** Solve the equation $$\frac{6}{x} + 6 = \frac{4}{7}$$ for $x$.
2. **Isolate the fraction term:** Subtract 6 from both sides:
$$\frac{6}{x} = \frac{4}{7} - 6$$
3. **Simplify the right side:** Convert 6 to a fraction with denominator 7:
$$6 = \frac{42}{7}$$
So,
$$\frac{6}{x} = \frac{4}{7} - \frac{42}{7} = \frac{4 - 42}{7} = \frac{-38}{7}$$
4. **Rewrite the equation:**
$$\frac{6}{x} = \frac{-38}{7}$$
5. **Cross multiply to solve for $x$:**
$$6 \times 7 = -38 \times x$$
$$42 = -38x$$
6. **Divide both sides by -38:**
$$x = \frac{42}{-38}$$
Show cancellation:
$$x = \frac{\cancel{42}}{\cancel{38}} \times \frac{2}{2} = \frac{21}{-19} = -\frac{21}{19}$$
7. **Final answer:**
$$x = -\frac{21}{19}$$
