Paul is solving for x. He shows his work as follows: Step 1: 3x + 2 = 7x - 2
Step 2: 2 = 4x - 2
Step 3: 4 = 4x
Step 4: X = 1
When Paul checks his answer, he thinks he’s made a mistake At which step did Paul make a mistake?

This is correct

Step-by-step explanation:

Paul has made no mistakes but he probably is wondering if the 4x that he got in the equation is correct.  He might second guess that he shouldn't have subtracted the 3x from the 7x but instead divided the two numbers.
