3.17

  1. Simplify:   7 – [pic] – [pic] + 5

4.12B

  1. Solve the system of equations:   x [pic] 3y = 12 and y = [pic] by substitution.

  2. Solve the system of equations:   2x – 4y = 12 and 2x + y = 2 by elimination.

  3. If you solve a system of equations and end up with a clearly true statement such as 2=2, x=x or 5=5, what does that tell you about the two lines?

  4.   If you solve a system of equations and end up with something like 6=2 or 8=5, something that is obviously not true, what does that tell you about the two lines?
