Determine whether the equation defines y as a function of x.
xy + 5y = 1
yes or no
--------------
Yes, it does. y can be expressed as a function of x, meaning y can be isolated on one side of the equal sign.
xy + 5y = 1
x + 5 = 1/y
y = 1/(x+5)
Note that for x = -5 the DEN is zero, so that's excluded.
