Answer

Final Answer: The solution to the equation is \(\boxed{-\frac{1}{2}}\).

Steps

Step 1 ：Distribute the 9 on the left side of the equation to get \(18x + 27 = 72x + 63\).

Step 2 ：Subtract 18x from both sides to get \(27 = 54x + 63\).

Step 3 ：Subtract 63 from both sides to get \(-36 = 54x\).

Step 4 ：Divide both sides by 54 to solve for x, which gives \(x = -\frac{2}{3}\).

Step 5 ：Final Answer: The solution to the equation is \(\boxed{-\frac{1}{2}}\).
