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.
