Determine whether the ordered air is s solution of the given system of equations, remember to use alphabetical order of variables. (5,2); a+b=7 and 2a-8=b
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.
