Answered by Damon
2. x + 3 > 2x + 1 and -4x < -8
note if you divide by negative number, change arrow direction
2 > x and x > 2 can not be both
Answered by Damon

4. -3x > -6 or x - 5 < 2
x < 2
or x < 7
everything left of seven satisfies the second, everything left of 2 satisfies both. In other words x<2 is a subset of x <7
Answered by Damon
5. x - 2 > 2x + 1 or 10 > -2x + 2
x < -2 or x > -4
that is everywhere
