Lets set up a simple equation to solve this problem.

Let x = your number.

(x - 2) * 2 = 5. To solve for x, divide each side by 2

(x - 2) = 5/2. Add 2 to each side.

x = 4.5 or 9/2

Answer:

2*(n-2) =5

n= 4.5

Explanation:

Twice the difference of a number and 2 equals 5

2*(n-2) =5

Distribute

2n-4 =5

Add 4 to each side

2n-4+4 = 5+4

2n = 9

Divide each side by 2

2n/2 = 9/2

n = 4.5
