Solution Steps

To evaluate the expression \(4 + 7z\) for \(z = 3\), we need to substitute \(z\) with 3 and then perform the arithmetic operations.

Step 1: Substitute the Value of \( z \)

We start with the expression \( 4 + 7z \) and substitute \( z = 3 \): \[ 4 + 7(3) \]

Step 2: Perform the Multiplication

Next, we calculate the multiplication: \[ 7(3) = 21 \]

Step 3: Add the Results

Now, we add the result of the multiplication to 4: \[ 4 + 21 = 25 \]

Final Answer

The final result of the expression is \(\boxed{25}\).
