Ms. JL
Many of you sent in excellent solutions to this problem!!! You tackled it using logic, order of operation, and algebra these are all great ways to go about solving the problem!
Here is the way the author of the problem saw the answer.
Please go back and look at the ways your peers solved the problem. Feel free to post comments, questions, or commend your peers for the way they approached the problem.
If x is the number you think of, you start with x,
Then when you add 1, you get x + 1
When you double it, it turns into 2x + 2
When you take away 3, it turns into 2x -1
Adding the number you first thought of makes 3x -1
When you add 7 it turns into 3x + 6
When you divide by 3 it turns into 1x + 2
Then take away the number you first thought of (x) it leaves 2.
See you Monday,
Ms. Leckman
