The correct answer is "<span>Step 2; 6x − 8 = 12 + 2x."
</span>
The step that the student first make an error is at the 2nd step. The correct step should be 6x − 8 = 12 + 2x.
Finishing the steps:
<span>Step 1: 2(3x − 4) = 8 + 2x + 4
</span>Step 2: <span>6x − 8 = 12 + 2x.
Step 3: 4x = 20
Step 4: x = 5</span>

Since there is no condition whatsoever for this arrangement, I can consider the 2 digits and the 5 letters as 7 different objects.
Total permutation (with no repetition):
7 chosen among 7 , that is 7 ! = 5040 arrangements
Total permutation (WITH REPERTITION):
7⁷ = 823 543
