Thank You
just solve the way you do an equation. Apply a step to all parts of the setup:
-1 < 3+2x < 11
subtract 3:
-4 < 2x < 8
divide by 2
-2 < x < 4
Ta-da!
The other is even easier, since each is separate
1-x > -3
1+3 > x
4 > x
5x-1 > 19
5x > 20
x > 4
So, x can be anything but 4.
x in (-∞,4)U(4,∞)
