Then Classify the system. x+y=13 x-y= -5Answer by drj(1380)   (Show Source): You can put this solution on YOUR website!Solve the system of equations by graphing. Then Classify the system. x+y=13 x-y= -5 Step 1. Graph the two lines as shown below Step 2. Based on the graph the solution is x=4, y=9 or point (4,9) Step 3. Check if (4,9) satisfies the original solutin 4+9=13 which is a true statement 4-9=-5 which is a true statement Step 4. ANSWER: The solution is (4,9). So the system of equations are independent, consistent and unique. I hope the above steps were helpful.
