In order to solve this exercise your need to remember the following:

- The word "less" indicates a subtraction.

- The "product" is the result of a multiplication.

- The word "equals" indicates that the symbol is "=".

Let be "n" the number mentioned in the exercise.

Knowing the above, you can determine that "the product of 3 and a number" can be written as:


3n

You also know that "seven less than the product of 3 and a number" is:


3n-7

Therefore, you can express "seven less than the product of 3 and a number equals 9" as following:


3n-7=9

The answer is:


3n-7=9
