How to solve:
      Problem 1.
When multiplying or dividing both sides
of an inequality by a positive number,
the direction of the inequality
stays the same.
      Problem 2.
When multiplying or dividing both sides
of an inequality by a negative number,
the direction of the inequality
must be switched:
< switches to >, etc.
Solve for x:     3x + 4 < 19.       -5x + 4 < -11
Subtract 4 from both sides:     3x + 4 - 4 < 19 - 4.       -5x + 4 -4 < -11 - 4
Simplify:     3x < 15.       -5x < -15
Divide:     3x/3 < 15/3.       -5x/(-5) > -15/(-5)
Simplify:     x < 5.       x > 3
