Question

решить ребус : АА+АВ=21

Answer 1

A=1
B=0
АА+АВ=21
11+10=21

Answer 2

Решим данный ребус: АА + АВ = 21.

Step 1:

Let's assign variables to the digits in the equation. Since we have two digits, we can assign the variable A to the tens digit and B to the units digit. Therefore, the equation becomes 10A + A + 10A + B = 21.

Step 2:

Simplifying the equation, we get 21A + B = 21.

Step 3:

Since the equation involves a single-digit number, we can try different values for A and B to find the solution.

Let's start with A = 1. Substituting A = 1 into the equation, we get 21 + B = 21. Solving for B, we find that B must be 0.

Therefore, one possible solution is A = 1 and B = 0, which means 10 + 10 + 1 + 0 = 21.

It's important to note that there might be other possible solutions as well. However, without additional information or constraints, we cannot determine the unique solution.

I hope this helps! Let me know if you have any further questions.
