1. **State the problem:** Simplify the expression $$1 - 5 - 2 - 3y - 3y$$ by combining like terms. 2. **Identify like terms:** Like terms are terms that have the same variable raised to the same power. Here, the constants are $$1, -5, -2$$ and the terms with $$y$$ are $$-3y$$ and $$-3y$$. 3. **Combine the constant terms:** $$1 - 5 - 2 = 1 - \cancel{5} - \cancel{2} = 1 - 7 = -6$$ 4. **Combine the $$y$$ terms:** $$-3y - 3y = -6y$$ 5. **Write the simplified expression:** $$-6 - 6y$$ **Final answer:** $$-6 - 6y$$
