The first step to solving this is to remember our mathematical rules. They state that when the term has a coefficient of -1,, the number doesn't have to be written but the sign needs to remain. This will change the expression to the following: x - v + 4 + 7y - 3 Now subtract the numbers 4 and 3 from each other. x - v + 1 + 7y Since this expression cannot be simplified any further,, the correct answer to your question would be x - v + 1 + 7y. Let me know if you have any further questions. :)
