Hey! Here's your answer!
Let digits be x and y.
x + y = 14
x = 2y - 1
By substituting the value of x n this equation,
2y - 1 + y = 14
3y = 15
y = 5
So, x = 9
The number is 95.
Hope this helps! :)

Thank you very much
No Problem! :)
Substitute means what
We know the value of x, so we put that value, which is on terms of y, in the another equation which contains x and y. So we get only y as a variable and then we can solve it as an equation in one variable. It is called simultaneous equations in two variables, where we get value of one variable i terms of other and then solve to find the answer.
