Hi Ace. Let's break this problem down into steps.

Step 1: State the meaning of all mathematical phrases in the problem.

"two times a number" - 2x, where x represents the unknown number; means multiplying 2 by the unknown number, x

"14 less then" - to subtract 14

"greater than" - is represented by the > sign: means all possible values of x that are more than 3 and that satisfy the inequality (make the inequality true)
