Solve Fraction Equation A02C53
1. **State the problem:** Solve the equation $$\frac{2x + 1}{4} + \frac{6x + 2}{5} = \frac{1}{4}$$ to find the value of $x$.
2. **Identify the formula and rules:** To solve equations with fractions, find a common denominator to clear the fractions by multiplying both sides of the equation.
3. **Find the least common denominator (LCD):** The denominators are 4, 5, and 4. The LCD is 20.
4. **Multiply every term by 20 to clear denominators:**
$$20 \times \frac{2x + 1}{4} + 20 \times \frac{6x + 2}{5} = 20 \times \frac{1}{4}$$
5. **Simplify each term:**
$$5(2x + 1) + 4(6x + 2) = 5$$
6. **Distribute:**
$$10x + 5 + 24x + 8 = 5$$
7. **Combine like terms:**
$$34x + 13 = 5$$
8. **Isolate $x$:**
$$34x = 5 - 13$$
$$34x = -8$$
9. **Solve for $x$:**
$$x = \frac{-8}{34} = \frac{-4}{17}$$
**Final answer:** $x = \frac{-4}{17}$ which corresponds to option b).
