Answer:

We can solve this problem by setting up an equation. Let’s use a variable, say x, to represent the unknown number.

The problem states:

  1. Subtract 3 from the number: x - 3
  2. Multiply the result by 2: 2(x - 3) = 8

Now, we solve the equation:

  1. Distribute the 2: 2x - 6 = 8
  2. Add 6 to both sides to isolate the term with x: 2x = 14
  3. Divide by 2 to solve for x: x = 7

So, the number is 7.

Summary: To find the number, set up the equation 2(x - 3) = 8, solve for x, and you find that the number is 7.
