The work of a student to solve the equation 4(2x β 4) = 8 + 2x + 8 is shown below: Step 1: 4(2x β 4) = 8 + 2x + 8
Step 2: 6x β 8 = 16 + 2x
Step 3: 6x β 2x = 16 + 8
Step 4: 4x = 24
Step 5: x = 6
In which step did the student first make an error and what is the correct step? Group of answer choices
Step 2; 8x β 4 = 2(6 + x + 6)
Step 2; 8x β 16 = 16 + 2x Step 3; 6x β 2x = 16 β 8
Step 3; 6x + 2x = 16 + 8
