Apologies for the confusion earlier. Upon further review, it appears that there was a mistake in Step 1 of solving the equation.

Step 1 should have been: 3x - 7 = 2 + x
Adding 7 to both sides gives: 3x = 9 + x

Therefore, the correct steps to solving the equation should be:

Step 1: 3x - 7 = 2 + x (initial equation)
Step 2: 3x = 9 + x
Step 3: 2x = 9
Step 4: x = 9/2

So, the mistake occurred in Step 1 where the x term wasn't correctly combined. Thank you for pointing that out.
