Find the values of the letters and give reasons for the steps involved. `12A + 6AB =A09` |
|
Answer» `12A+6AB = A09` Here, we can see that , `A+B = 9->(1)` `2+A = 0->(2)` `1+6 = A->(3)` From (2), we can see that possible values for `A` is `8` or `7`. For `A` to be `7`, `A+B` should be greater that `9` that is not possible from `(1)`. So, value of `A` is `8`. From (1), we can see that if `A` = `8`, then `B = 9 - 8= 1` So, `A = 8 and B=1` |
