(1, -3) x + y = -2 x - y = 4This question is from textbook Answer by jim_thompson5910(28717)   (Show Source): You can put this solution on YOUR website!Let's see if and satisfy the first equation. Start with the first equation. Plug in and . Subtrac Since the equation is true, this means that and satisfy the first equation. -------------------------------------------------------- Let's see if and satisfy the second equation. Start with the second equation. Plug in and . Rewrite as Add Since the equation is true, this means that and satisfy the second equation. Since ALL of the equations of the system are satisfied (ie they are true for the given values) , this means that (1,-3) is a solution to the given system. Note: a longer alternative is to solve the system (using any method) and find the true solution, which you'll find is (1,-3).
