D. When you substitute for the variables the equation becomes -1-5×6=-31. First, you multiply -5 by 6 to get -30. This makes the equation -1-30=-31. -1-30 is -31 so your equation is now -31=-31.
The mistake he made was that he multiplied 2 and 3, equaling 6. But what he SHOULD have done was multiply 2 * 2 * 2 to get 8
