1. **State the problem:** Solve the equation $16x - x - 8x = -14$ for $x$. 2. **Combine like terms:** On the left side, combine the terms with $x$: $$16x - x - 8x = (16 - 1 - 8)x = 7x$$ So the equation becomes: $$7x = -14$$ 3. **Isolate $x$:** To solve for $x$, divide both sides by 7: $$\frac{\cancel{7}x}{\cancel{7}} = \frac{-14}{7}$$ 4. **Simplify the right side:** $$x = -2$$ **Final answer:** $x = -2$
