Solution Steps

Step 1: Isolate the Variable Term

To solve the equation \(3b - 39 = -78\), we first isolate the term containing the variable \(b\). We do this by adding 39 to both sides of the equation:

\[ 3b - 39 + 39 = -78 + 39 \]

This simplifies to:

\[ 3b = -39 \]

Step 2: Solve for the Variable

Next, we solve for \(b\) by dividing both sides of the equation by 3:

\[ b = \frac{-39}{3} \]

This simplifies to:

\[ b = -13 \]

Final Answer

The solution to the equation is \(\boxed{b = -13}\).
