Solve Rational Equation 0F847D
1. **State the problem:** Solve the equation $$\frac{5}{x-1} + \frac{1}{4-3x} = \frac{3}{6x-8}$$ for $x$.
2. **Rewrite the denominators:** Notice that $$4-3x = -(3x-4)$$ and $$6x-8 = 2(3x-4)$$.
3. **Find a common denominator:** The denominators are $x-1$, $4-3x$, and $6x-8$. Since $4-3x = -(3x-4)$ and $6x-8=2(3x-4)$, the common denominator can be taken as $2(x-1)(3x-4)$.
4. **Multiply both sides by the common denominator to clear fractions:**
$$2(x-1)(3x-4) \times \left( \frac{5}{x-1} + \frac{1}{4-3x} \right) = 2(x-1)(3x-4) \times \frac{3}{6x-8}$$
5. **Simplify each term:**
- First term: $$2(x-1)(3x-4) \times \frac{5}{x-1} = 2(3x-4) \times 5 = 10(3x-4)$$
- Second term: $$2(x-1)(3x-4) \times \frac{1}{4-3x} = 2(x-1)(3x-4) \times \frac{1}{-(3x-4)} = -2(x-1)$$
- Right side: $$2(x-1)(3x-4) \times \frac{3}{2(3x-4)} = 3(x-1)$$
6. **Write the equation after clearing denominators:**
$$10(3x-4) - 2(x-1) = 3(x-1)$$
7. **Expand terms:**
$$30x - 40 - 2x + 2 = 3x - 3$$
8. **Combine like terms:**
$$30x - 2x = 28x$$
$$-40 + 2 = -38$$
So the equation becomes:
$$28x - 38 = 3x - 3$$
9. **Bring all terms to one side:**
$$28x - 3x = -3 + 38$$
$$25x = 35$$
10. **Solve for $x$:**
$$x = \frac{35}{25} = \frac{7}{5} = 1.4$$
11. **Check for restrictions:**
Denominators cannot be zero:
- $x-1 \neq 0 \Rightarrow x \neq 1$
- $4-3x \neq 0 \Rightarrow x \neq \frac{4}{3} \approx 1.333$
- $6x-8 \neq 0 \Rightarrow x \neq \frac{8}{6} = \frac{4}{3} \approx 1.333$
Since $x=1.4$ is not equal to any restricted value, it is valid.
**Final answer:** $$\boxed{x = \frac{7}{5}}$$
