What is your solution set for x + y = 0 x - y + 2 = 0
There are two methods to solve this question : 1) Substitution 2)Elimination Which one would you prefer ?
idk, this is what the question says, Using a sheet of graph paper, solve the following system of equations graphically. Be sure to show any work, use a straight edge, and be neat. When you are finished, enter the solution set in the box below and turn in your graph paper to your teacher.
@hrcheerlove Lets solve it by elimination, Add the two equations.
i dont know how to though

@hrcheerlove Lets see I told you to add them up x + y = 0 x - y + 2 = 0 ------------- < Try adding them up and tell me what you get. --------------
