Question 151675
We need to set up an equation.

Let x be the number.

The diffrence of a number and one is x - 1.
Five times the diffrence of a number and one is 5(x - 1)

Twice the same number is 2x.
Twice the same number increase by three is 2x +3

So
5(x - 1) = 2x +3

Solving for x we obtain:
5x - 5 = 2x + 3
3x = 8
x = 8/3

Therefore the number is 8/3.
