AB
If B = x, then A = x + 4
Also, A = 2x -1
So that,
2x - 1 = x + 4
x = 5
B = 5, A = 9
So AB = 95

let x- unit digit 2x + 1- twice the tens by one x + 2x +1 = 10 x + 2x = 10 - 9 3x= 9 x = 3 therefore : x = 3 2x + 1 = 7 the number is 37. you can try checking it: x + 2x + 1 = 10 3 + 2(3) = 10-1 3 + 6 = 9 9 = 9
18 is the only number that matches these criteria.
