1. **State the problem:** Simplify the expression $6m - 6 + 8m$. 2. **Identify like terms:** The terms $6m$ and $8m$ are like terms because they both contain the variable $m$. 3. **Add the like terms:** $$6m + 8m = (6 + 8)m = 14m$$ 4. **Rewrite the expression:** $$14m - 6$$ 5. **Final simplified expression:** $$14m - 6$$ This is the simplified form of the original expression.
