If you have done this problem completely correctly in Lesson 14, you can turn in your previous work.

*Regarding 4.8: Assume that  x  is not 1.  Use an equivalent form of  “IF  p THEN ( q OR  r)”  (see extra problem in Lesson 5) to change the statement you are given to an equivalent, simpler statement (simpler in the sense that it is easier to prove).
