Demarcus Harrington · Answer 1

Given your ordered pair you would assume a = 5, b = 2

Set up both equations

5 + 2 = 7

7 = 7 (the numbers are equal so this correct)

2 (5) - 8 = 2

10 - 8 = 2

2 = 2 (the numbers are equal so this is also correct)

Because both equations work with the ordered pair they are the solution of the given system.
