1. **State the problem:** Solve the system of linear equations:
$$9x - 2y = -50$$
$$-3x + 7y = 4$$
2. **Choose a method:** We will use the elimination method to solve for $x$ and $y$.
3. **Eliminate one variable:** Multiply the second equation by 3 to align coefficients of $x$:
$$3(-3x + 7y) = 3(4)$$
$$-9x + 21y = 12$$
4. **Add the two equations:**
$$9x - 2y = -50$$
$$-9x + 21y = 12$$
Adding gives:
$$\cancel{9x} - 2y + \cancel{-9x} + 21y = -50 + 12$$
$$19y = -38$$
5. **Solve for $y$:**
$$y = \frac{-38}{19} = -2$$
6. **Substitute $y = -2$ into the first equation:**
$$9x - 2(-2) = -50$$
$$9x + 4 = -50$$
7. **Solve for $x$:**
$$9x = -50 - 4$$
$$9x = -54$$
$$x = \frac{-54}{9} = -6$$
**Final answer:**
$$x = -6, \quad y = -2$$
