Solve the following system of equations graphically. click on the graph until the correct solution of the system appears. y = -3 x - y = 8

X-(-3)=8
x + 3 = 8
   -3     -3
x=5

5 - (-3) = 8
5 + 3 = 8 

You can plug in y by writing x - ( -3 ) = 8 so now you just sove it as a one step equation do the inverse operation by adding - 3 to 8 making it x - (- 3 ) = 8
                                                                                                               +  - 3 
                                                                                                           
                                                                                                                  - 5
which by doing the inverse it cancels out -3 which leaves x by itself so x  = -5
