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.
