Answer

The ordered pair that is a solution for this system is (4,5). This is X= 4 and Y= 5.

Work Step by Step

When finding the solution to a system of equations using a table, the coordinate that returns the same Y1 and Y2 value is considered to be the solution. In our case, there is only one value of X that returns the same value for both Y1 and Y2. By analyzing the table we created using the functions tblset and 2nd + Graph, it is clear that only X=4 can be a solution for this system, which returns a value of 5 for both equations.
