A student used the following steps to show that -3(x + 4) - 5(x + 3) is equivalent to - 8x + 27:
Step 1: -3x + 12 - 5x + 15
Step 2: -3x + -5x + 12 + 15
Step 3: -8x + 27
The student made a mistake.
In which step did the student first make a mistake, and what is a correct expression for that step?
Step 1; -3x + 1 - 5x – 2
Step 1; -3x - 12 - 5x – 15
Step 3; -2x + 27
Step 3; 2x + 27
