Strategy for 1 over y

[Jason76]

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.

y = 1 / (-x - E)

Ok, got it, thanks.

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

The free video said to do that, but I guess either way (working it out or inverting) will work.
