1. **State the problem:** Solve the system of linear equations:
$$-7x + 5y = -17$$
$$-8x + 3y = 5$$
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 3 and the second equation by 5 to align coefficients of $y$:
$$3(-7x + 5y) = 3(-17) \Rightarrow -21x + 15y = -51$$
$$5(-8x + 3y) = 5(5) \Rightarrow -40x + 15y = 25$$
4. **Subtract the two equations to eliminate $y$:**
$$(-21x + 15y) - (-40x + 15y) = -51 - 25$$
$$-21x + 15y + 40x - 15y = -76$$
$$(-21x + 40x) + (15y - 15y) = -76$$
$$19x + 0 = -76$$
5. **Solve for $x$:**
$$19x = -76$$
$$x = \frac{-76}{19}$$
$$x = -4$$
6. **Substitute $x = -4$ into the first original equation to find $y$:**
$$-7(-4) + 5y = -17$$
$$28 + 5y = -17$$
7. **Isolate $y$:**
$$5y = -17 - 28$$
$$5y = -45$$
$$y = \frac{-45}{5}$$
$$y = -9$$
**Final answer:**
$$x = -4, \quad y = -9$$
