Sherry uses the steps below to solve the equation x + (negative 8) = 3 x + 6.

Step 1 Add 1 negative x-tile to both sides and create zero pairs
Step 2 Add 8 positive unit tiles to both sides and create zero pairs.
Step 3 Divide the 14 unit tiles evenly among the 2 x-tiles.
Step 4 The solution is x = 7

What is Sherry’s error?
O In step 1, she should have added 3 negative x-tiles to both sides.
O In step 2, she should have added 6 negative unit tiles to both sides.
O step 3, she did not divide the tiles evenly.
O In step 4, she should have found the solution x = negative 1.
