Question

find the value of A and B in each of the following
a. A08+1A=AA0​

Answer 1

Answer:

A= 2

B= 8

Step-by-step explanation:

A 0 B + 1 A = AA0

*look for 2 numbers that add up to 10, b'coz we need the ones to be 0

1 and 9

2 and 8

3 and 7

4 and 6

5 and 5

▪︎so let's try 9 to be our B and 1 for our A

*A must be smaller than B

A0B + 1A=AA0

109 + 11= 120

*1 and 9 are not compatible

▪︎now let's try 8 to be our B and 2 for our A

A0B+1A=AA0

208 + 12=220

*2 and 8 are correct

▪︎let's try 7 to be our B and 3 for our A

A0B+1A=AA0

307+13=310

*not compatible as well

▪︎then, let's try 6 to be our B and 4 for our A

A0B+1A=AA0

406+14=420

*not compatible also

▪︎5 and 5 cannot be because A and B must be 2 different numbers...
