Five times a number decreased by twice the same number.

5N-2N

5n - 2n =

N+9

the difference of n and 12 is greater than 13

n-12

43-12=31
31>13

To solve this problem, let's break it down step by step.

Step 1: Let's assign a variable to the number in question. Let's call it "x". So, the problem now becomes: 5x - 2x.

Step 2: Simplify the expression. 5x - 2x simplifies to (5 - 2)x.

Step 3: Perform the operation (5 - 2). 5 minus 2 equals 3, so the expression simplifies further to 3x.

Therefore, the answer to the question "Five times a number decreased by twice the same number" is 3x.
