Step 2(?) the step with 15 - 3e
When combining 9 = -3e + 6, six would be subtracted from nine equaling three not fifteen. 
Correct Steps:
Equation: 9 = -3 (e - 2)
Step 1: 9 = -3e + 6
          - 6           - 6
            3 = -3e
Step 2: 3 = -3e
            /-3   /-3
             -1 = e
Answer: -1 = e
