1. **State the problem:**
We have two separate equations involving fractions:
Equation 1: $$\frac{x - 2}{2} = \frac{1 - 9}{2x}$$
Equation 2: $$\frac{x - 1}{3x} = \frac{x - 3}{9x}$$
2. **Solve Equation 1:**
Start by simplifying the right side numerator:
$$1 - 9 = -8$$
So the equation becomes:
$$\frac{x - 2}{2} = \frac{-8}{2x}$$
3. Cross-multiply to eliminate denominators:
$$ (x - 2) \cdot 2x = 2 \cdot (-8) $$
Simplify:
$$ 2x(x - 2) = -16 $$
4. Expand the left side:
$$ 2x^2 - 4x = -16 $$
5. Bring all terms to one side:
$$ 2x^2 - 4x + 16 = 0 $$
Divide entire equation by 2 to simplify:
$$ x^2 - 2x + 8 = 0 $$
6. Use the quadratic formula to solve for $x$:
$$ x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} $$
where $a=1$, $b=-2$, $c=8$.
Calculate discriminant:
$$ \Delta = (-2)^2 - 4 \cdot 1 \cdot 8 = 4 - 32 = -28 $$
Since $\Delta < 0$, there are no real solutions for Equation 1.
7. **Solve Equation 2:**
$$ \frac{x - 1}{3x} = \frac{x - 3}{9x} $$
8. Cross-multiply:
$$ (x - 1) \cdot 9x = (x - 3) \cdot 3x $$
Simplify both sides:
$$ 9x(x - 1) = 3x(x - 3) $$
9. Expand both sides:
$$ 9x^2 - 9x = 3x^2 - 9x $$
10. Bring all terms to one side:
$$ 9x^2 - 9x - 3x^2 + 9x = 0 $$
Simplify:
$$ 6x^2 = 0 $$
11. Divide both sides by 6:
$$ x^2 = 0 $$
12. Solve for $x$:
$$ x = 0 $$
13. **Check for restrictions:**
In Equation 2, denominators are $3x$ and $9x$, so $x \neq 0$ to avoid division by zero.
Therefore, $x=0$ is not a valid solution.
14. **Final answers:**
- Equation 1 has no real solutions.
- Equation 2 has no valid solutions because $x=0$ is excluded.
Hence, both equations have no real solutions under the given conditions.
