1. **State the problem:** Solve the system of linear equations:
$$3x + 4y = 14$$
$$5x - 2y = 3$$
2. **Choose a method:** We will use the elimination method to solve for $x$ and $y$.
3. **Eliminate one variable:** Multiply the first equation by 2 and the second equation by 4 to align coefficients of $y$:
$$2(3x + 4y) = 2(14) \Rightarrow 6x + 8y = 28$$
$$4(5x - 2y) = 4(3) \Rightarrow 20x - 8y = 12$$
4. **Add the two equations to eliminate $y$:**
$$6x + 8y + 20x - 8y = 28 + 12$$
$$ (6x + 20x) + (8y - 8y) = 40$$
$$26x = 40$$
5. **Solve for $x$:**
$$x = \frac{40}{26} = \frac{20}{13}$$
6. **Substitute $x$ back into one of the original equations to find $y$:** Using the first equation:
$$3\left(\frac{20}{13}\right) + 4y = 14$$
$$\frac{60}{13} + 4y = 14$$
7. **Isolate $y$:**
$$4y = 14 - \frac{60}{13} = \frac{182}{13} - \frac{60}{13} = \frac{122}{13}$$
8. **Solve for $y$:**
$$y = \frac{122}{13} \times \frac{1}{4} = \frac{122}{52} = \frac{61}{26}$$
**Final answer:**
$$x = \frac{20}{13}, \quad y = \frac{61}{26}$$
