Final answer:

To solve the problem, we need to create an equation and solve it step by step. The number you thought of is 9.

Step-by-step explanation:

To solve this problem, we can follow the given steps:

  1. Let's assume the number you thought of is 'x'.
  2. Double the number: 2x
  3. Add 9 to the doubled number: 2x + 9
  4. Set the sum equal to 27: 2x + 9 = 27
  5. Now, solve the equation to find the value of 'x'. Start by subtracting 9 from both sides: 2x = 27 - 9 = 18
  6. Next, divide both sides of the equation by 2 to isolate 'x': x = 18/2 = 9

The number you thought of is 9
