The work of a student trying to solve the equation 2(2x β 3) = 6 + 2x + 4 is shown below:
Step 1: 2(2x β 3) = 6 + 2x + 4
Step 2: 4x β 3 = 10 + 2x
Step 3: 4x β 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? (4 points)
Group of answer choices
Step 3: 4x + 2x = 10 + 3
Step 2: 4x β 3 = 2 + 2x
Step 3: 4x β 2x = 10 - 3
Step 2: 4x β 6 = 10 + 2x
