Please help! They are asking for 2 solution sets and I don't know where to start. Thanks in advance!
Solve and write interval notation for the solution set.
3 – 8x < –5 or 3 – 8x > 19

Solve each part independently:
3  8x < 5
8x < 8
x > 1
3  8x > 19
8x > 16
x < 2
Therefore, the solution is [infinity, 2] and [1, infinity]

Would this
[infinity, 2] and [1, infinity]
be the same and equal
(infinity sign,2, U(1,infinity sign)

Yes. I should have used parentheses.

It's ok, I see how this is the answer now! Thanks again for your help!
