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

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.

In which step is the error? Step 1: Let x = 1 and y = 1. Step 2: By substitution xy = y^2. Step 3: Multiplying both sides by 1, xy= y^2. Step 4: Adding x^2 to both sides, x^2xy=x^2y^2. Step 5: Factoring, x(xy)=(x+y)(xy). Step
