The work of a student to solve the equation
2(3x − 4) = 8 + 2x + 4 is shown below:
step 1: 2(3x − 4) = 8 + 2x + 4
step 2: 5x − 6 = 12 + 2x
step 3: 5x − 2x = 12 + 6
step 4: 3x = 18
step 5: x = 6

in which step did the student first make an error and what is the correct step?

the number of possible outcomes that do not show a 1 on the first spinner and show the number 4 on the second spinner is 2.
