The work of a student trying to solve the equation 3 (4x - 2) = 9 + 2x + 5 is shown below:
Step 1: 3 (4x - 2) = 9 + 2x + 5
Step 2: 12x - 2 = 14 + 2x
Step 3: 12x - 2x = 14 + 2
Step 4: 10x = 16
Step 5: x = 1.6
In which step did the student first make an error and what is the correct step?
A.) Step 2: 12x - 2 = 4 + 2x
B.) Step 2: 12x - 6 = 14 + 2x
C.) Step 3: 12x + 2x = 14 + 2
D.) Step 3: 12x - 2x = 14 - 2
