Using the substitution method, we can substitute y-4 for x in the second equation:
(y-4) + 8y = 2
9y - 4 = 2
9y = 6
y = 2/3
Now, substitute y = 2/3 back into the first equation:
x = (2/3) - 4
x = -10/3
Therefore, the solution is x = -10/3 and y = 2/3, which in fraction form is (-3 1/3, 2/3).
So the correct response is: left parenthesis negative 3 Start Fraction 1 over 3 End Fraction comma Start Fraction 2 over 3 End Fraction right parenthesis
