In many cases, you get \(\displaystyle \dfrac{1}{y}\) on one side of the equation. Therfore, you need to get the y to the numerator on one side alone (as with the case in graphing equations).

What about in this case?

\(\displaystyle \dfrac{1}{y} = -x - E\)

\(\displaystyle \dfrac{1}{y}(y) = -x(y) - E(y)\)

\(\displaystyle 1 = -xy - Ey\)

\(\displaystyle 1 = y(-x - E)\)

What would be the next move?

If you have 1/y equal to an expression, just invert both sides.
