Need ! the work of a student to solve the equation 2(4x − 4) = 8 + 4x + 4 is shown below: step 1. 2(4x − 4) = 8 + 4x + 4 step 2. 6x − 6 = 12 + 4x step 3. 6x − 4x = 12 + 6 step 4. 2x = 18 step 5. x = 9 in which step did the student first make an error and what is the correct step?
step 2, 8x − 6 = 2(6 + 2x + 2)
step 2, 8x − 8 = 12 + 4x
step 3, 6x − 4x = 12 − 6
step 3, 6x + 4x = 12 + 6
