1. **State the problem:** Solve the system of equations:
$$5y = 2x - 6$$
$$3x - 2y = -10$$
2. **Rewrite the first equation to express $y$ in terms of $x$: **
$$5y = 2x - 6$$
$$y = \frac{2x - 6}{5}$$
3. **Substitute $y$ into the second equation:**
$$3x - 2\left(\frac{2x - 6}{5}\right) = -10$$
4. **Multiply both sides by 5 to clear the denominator:**
$$5 \times 3x - 5 \times 2 \times \frac{2x - 6}{5} = 5 \times (-10)$$
$$15x - 2(2x - 6) = -50$$
5. **Distribute and simplify:**
$$15x - (4x - 12) = -50$$
$$15x - 4x + 12 = -50$$
$$11x + 12 = -50$$
6. **Isolate $x$:**
$$11x = -50 - 12$$
$$11x = -62$$
$$x = \frac{-62}{11}$$
7. **Substitute $x$ back into the expression for $y$:**
$$y = \frac{2\left(\frac{-62}{11}\right) - 6}{5}$$
$$y = \frac{\frac{-124}{11} - 6}{5}$$
8. **Convert 6 to fraction with denominator 11:**
$$6 = \frac{66}{11}$$
9. **Simplify numerator:**
$$\frac{-124}{11} - \frac{66}{11} = \frac{-190}{11}$$
10. **Divide by 5:**
$$y = \frac{\frac{-190}{11}}{5} = \frac{-190}{11} \times \frac{1}{5} = \frac{-190}{55}$$
11. **Simplify fraction:**
$$\frac{-190}{55} = \frac{\cancel{-190}^{\times 5 \times 38}}{\cancel{55}^{\times 5 \times 11}} = \frac{-38}{11}$$
**Final solution:**
$$x = \frac{-62}{11}, \quad y = \frac{-38}{11}$$
