Step 1: Let's solve the following inequation and detecting where the mistake is:
-2 (x - 1) - 2 > 8 - 5x + 4 + x
-2x + 2 - 2 > 8 - 5x + 4 + x
-2x > 12 - 4x
Step 2: Like terms:
-2x + 4x > 12 (Here the mistake was made)
2x > 12
Step 3: Now you can simplify dividing by 2 at both sides and you'll have the value for x
