X> 1 x< -1 has no solution why

Because there are no numbers that are greater than 1 but also less than -1.  Numbers that are greater than one (x>1), are 2, 3, 4, 5, etc.  Numbers that are less than negative one (x<-1) are -2, -3, -4, -5, etc.  There is no overlap for these two numbers, therefore there is no solution that works for both of the inequalities.

Thats where they was ported and the fields that noone really knew much about needed tended, so they put slaves out there do free work and huge profits and so on the north decided to hold its own and was more different way of survival did not have same climate conditions to afford protecting slaves from winter so expenses be diff from south
