Question 175633
x+2 > 7 or 1-x > 6 
Isolate the "x":
x > 5 or -x > 5
Reverse the negative inequality:
x > 5 or x < 5
The OR means the solution is any number that is less than 5 or greater
than 5; than only excludes the number 5.
--------------------------------------------
So the solution is (-inf,5)OR(5,+inf.)
