Solution Steps

To solve the equation \(3(x+1)=18\), we need to isolate \(x\). First, divide both sides by 3 to undo the multiplication. Then, subtract 1 from both sides to solve for \(x\).

Step 1: Divide Both Sides by 3

Starting with the equation: \[ 3(x + 1) = 18 \] we divide both sides by 3: \[ x + 1 = \frac{18}{3} = 6 \]

Step 2: Subtract 1 from Both Sides

Next, we subtract 1 from both sides to isolate \(x\): \[ x = 6 - 1 = 5 \]

Final Answer

\(\boxed{x = 5}\)
