bobpursley,
You need to show some work. I think you are answer grazing.

SAP,
4x+5y=27
x=264y
4(264y) + 5y = 27
104  16y+ 5y = 27
21y =  77
21y = 77
y = 77/31
Now, I’m suppose to return to the 2nd equation x=264y 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.
