I'm assuming that the equation is y-x=5 right ? If I'm wrong, let me know.

Since we have the ordered pair (2,7), this means that x=2 and y=7


y-x=5 Start with the given equation


7-2=5 Plug in x=2 and y=7


5=5 Subtract


Since the equation is true, this means that ordered pair (2,7) is a solution to the equation y-x=5
