I am thinking of a number. When I add 8 and then multiply by 3, the result is 66. What is my number?

  • Which of the equations represent this problem? Select all that apply, and justify your choices.

x + 24 = 663

x + 24 = 66

3x + 8 = 66

3(x + 8) = 66

  • For each equation that you identified, find the value of x and explain what it represents.
