Six more than the product of a number and 7 is equal to 3 .

Step 1: Identify the unknown number
Let's assume the unknown number is "x."

Step 2: Translate "Six more than the product of a number and 7."
The "product of a number and 7" can be represented as (7 * x). "Six more" than this product can be represented as (7 * x + 6).

Step 3: Set up the equation
According to the problem, "Six more than the product of a number and 7 is equal to 3." This can be written as:

7 * x + 6 = 3

Step 4: Solve the equation
To solve for x, we need to isolate the variable on one side of the equation. Let's subtract 6 from both sides:

7 * x + 6 - 6 = 3 - 6
7 * x = -3

Now, divide both sides by 7 to solve for x:

(7 * x) / 7 = -3 / 7
x = -3 / 7

So, the value of x, or the unknown number, is -3/7.
