Question

Answer

The problem is to find the value of the digit A such that the equation is true.
The notation represents a two-digit number where both digits are A. This can be written as .
The notation represents a three-digit number where all digits are A. This can be written as .
So the equation can be rewritten as:
Combine the terms on the left side of the equation:

To find the value of A, divide both sides of the equation by 123:
Now, we need to perform the division. We can estimate the value of A. Since and , it seems that A is 6.
Let’s verify the multiplication:
.
So, .
Now let’s check if this value of A satisfies the original equation:




The equation is satisfied.
The final answer is .
