The work of a student trying to solve the equation 2 (2x - 3) = 6 + 2x + 4 is shown below: Step 1: 2 (2x - 3) = 6 + 2x + 4

Step 2: 4x - 3 = 10 + 2x

Step 3: 4x - 2x = 10 + 3

Step 4: 2x = 13 Step 5: x = 6.5 In which step did the student first make an error and what is the correct step?

Step 2: 4x - 6 = 10 + 2x Step 2: 4x - 3 = 2 + 2x Step 3: 4x + 2x = 10 + 3 Step 3: 4x - 2x = 10 - 3
