Question: User: 7(x+6)+18 = 9(x+1)-3
1. **State the problem:** Solve the equation $$7(x+6)+18 = 9(x+1)-3$$ for $x$. 2. **Write down the equation:** $$7(x+6)+18 = 9(x+1)-3$$ 3. **Apply the distributive property:** $$7 \times x + 7 \times 6 + 18 = 9 \times x + 9 \times 1 - 3$$ which simplifies to $$7x + 42 + 18 = 9x + 9 - 3$$ 4. **Combine like terms on each side:** $$7x + 60 = 9x + 6$$ 5. **Bring all terms involving $x$ to one side and constants to the other:** $$7x - 9x = 6 - 60$$ 6. **Simplify both sides:** $$\cancel{7x} - 9x = 6 - 60$$ $$-2x = -54$$ 7. **Divide both sides by $-2$ to solve for $x$:** $$x = \frac{-54}{-2}$$ 8. **Simplify the fraction:** $$x = 27$$ **Final answer:** $$x = 27$$
