$$
5(5 + b) = 120
$$
Here, $ a $ represents the constant 5, making this step simple: $ 5(5 + b) $ becomes the left-hand side before substituting.
Step 2: Simplify the equation
Distribute the 5 inside the parentheses:

$$
25 + 5b = 120
$$
Now the equation clearly shows the constant and variable terms, ready for the next step.
Step 3: Isolate the variable term
Subtract 25 from both sides to eliminate the constant on the left:
$$
5b = 120 - 25
$$
$$
5b = 95
$$
This reduces the equation to a simple form where the variable $ b $ can be isolated.
Step 4: Solve for $ b $
Divide both sides by 5:
