1. **State the problem:** Solve the equation $$7x - 4 - 6x - 14 = 30$$. 2. **Combine like terms:** Group the terms with $x$ and the constants. $$7x - 6x - 4 - 14 = 30$$ $$x - 18 = 30$$ 3. **Isolate $x$:** Add 18 to both sides to isolate $x$. $$x - 18 + 18 = 30 + 18$$ $$x = 48$$ 4. **Final answer:** The solution to the equation is $$\boxed{48}$$. This means $x$ equals 48, which matches one of the given choices.
