1. 4< 7 multiply both sides by 7, then by 6, then by 3, then by 10

2. 11> -2 add 5 to both sides, then add 3, then add (-4)

3. -4< -2 subtract 6 from both sides, then 8, and then 2

4. -8< 8 divide both sides by -4, then by -2

5. write a short explanation of the effects of the above operations. did this affect the inequality sign? was it still true? why or why not?
