We need to get X by itself, so we're going to multiply by the
reciprocal 4/5, because if I have 4/5 * 5 fourths, that's
going to give me one.
And if I multiply one side by 4/5, we have to multiply the
other side by 4/5.
So we're going to get X greater than or equal to -12 fortieths,
and -12 fortieths is going to reduce to -3 tenths, dividing
each of them by 4.
So our solution sets going to be the set of X such that X greater
than or equal to negative 3/10.
