Jaiden worked out his homework problem below. Choose the statement that best describes his work. Solve for x in the diagram below. Step 1: Step 2: Step 3:

All of Jaiden's work is correct. The solution is x = 31.

In step 1, Jaiden incorrectly set the expressions equal to each other instead of adding them together and setting the total equal to .

To get to step 2, Jaiden incorrectly subtracted 2x from both sides instead of adding 2x to both sides.

To get to step 3, Jaiden incorrectly added 8 to both sides instead of subtracting 23 from both sides.
