**SAP**, Thursday, September 30, 2010 at 9:36pm4x+5y=27

x=26-4y

4(26-4y) + 5y = 27

104 - 16y+ 5y = 27

-21y = - 77

21y = 77

y = 77/31

Now, I’m suppose to return to the 2nd equation x=26-4y and substitute 77/31 for x, I don’t understand if the is correct way or how to get the answer for the ordered pair.
