1. **State the problem:** Find the ordered pair $(x,y)$ that satisfies both equations:
$$-6x - 7y = 0$$
$$4x - 5y = 58$$
2. **Use the substitution or elimination method:** Here, we use elimination.
3. Multiply the first equation by 4 and the second by 6 to align coefficients of $x$:
$$4(-6x - 7y) = 4(0) \Rightarrow -24x - 28y = 0$$
$$6(4x - 5y) = 6(58) \Rightarrow 24x - 30y = 348$$
4. Add the two equations to eliminate $x$:
$$(-24x - 28y) + (24x - 30y) = 0 + 348$$
$$-24x + 24x - 28y - 30y = 348$$
$$-58y = 348$$
5. Solve for $y$:
$$y = \frac{348}{-58} = \frac{\cancel{58}6}{-\cancel{58}1} = -6$$
6. Substitute $y = -6$ into the first equation to find $x$:
$$-6x - 7(-6) = 0$$
$$-6x + 42 = 0$$
7. Solve for $x$:
$$-6x = -42$$
$$x = \frac{-42}{-6} = \frac{\cancel{6}(-7)}{-\cancel{6}1} = 7$$
8. **Final answer:** The ordered pair is $(7, -6)$.
This corresponds to option [D].
