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

2 * (n-2) = 5
n = 4.5
Step-by-step 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
