Answer 1

To correctly answer your question, I would need the specific system of equations that Vince solved, as well as the variables involved (e.g., x, y, etc.) and the values obtained after solving. The options provided (A, B, C, D) indicate different substitution methods with probably varying values. However, since you’ve not provided the equations or the details, I can’t determine which of the statements is accurate.

Please provide the specific equations or the context regarding the variables, and I'll be glad to help you identify the correct statement!
