Find the values of the letters and give reasons for the steps involved. `AB xx 5 = CAB`

Explanation

To solve the equation \( AB \times 5 = CAB \), we will break it down step by step.

### Step 1: Understand the Structure
The expression \( AB \) represents a two-digit number where \( A \) is the tens digit and \( B \) is the units digit. Therefore, we can express \( AB \) as:
\[ AB = 10A + B \]
Similarly, \( CAB \) represents a three-digit number where \( C \) is the hundreds digit, \( A \) is the tens digit, and \( B \) is the units digit, which can be expressed as:
