Eight less than the product of 6 and a number is equal to 9 .

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

Step 1: Let's assume the unknown number as "x".
So we can rewrite the problem as the equation:

6x - 8 = 9

Step 2: Now, let's isolate the variable "x" by moving the constant term to the other side of the equation.
To do that, we can add 8 to both sides of the equation:

6x - 8 + 8 = 9 + 8
6x = 17

Step 3: Finally, we can solve for "x" by dividing both sides of the equation by 6:

6x/6 = 17/6
x = 17/6

Therefore, the solution to the problem is x = 17/6.
