Answer 4

-2 < = 3 - 5x <= 18 -- subtract 3 from all sides
-2 - 3 <= 3 - 3 - 5x <= 18 - 3 -- combine like terms
-5 <= -5x <= 15 -- now divide by -5, and change the inequality signs
-5/-5 <= -5x/-5 <= 15/-5
1 >= x >= -3

any questions ?

Answer 5

or you could have also done it by seperating them..
-2 <= 3 - 5x
-2 - 3 <= -5x
-5 <= -5x
1 >= x

3 - 5x <= 18
-5x <= 18 - 3
-5x <= 15
x >= -3

leaving us with : -3 <= x <= 1

Answer 6

either way is correct
