Question 637426: this is only 1 problem out of 20. I tried reading the book and looking at examples but i still am not getting a good grasp of it. if you could please explain how and show the steps maybe i can get a better understanding of this. thank in advance.
My “and” compound inequality is
0<4+2x<22
My “or” compound inequality is
3x+6<-3 or 5-x<1
Solve the compound inequalities. Show all math work arriving at the solutions. Show the solution sets written algebraically and as a union or intersection of intervals. Describe in words what the solution sets mean, and then display a simple line graph for each solution.

for "and" compound inequalties, do it just like a regular single variable equation, except whatever you do to one part, you have to do to all three parts. Add -4 to all three parts:



Multiply all three parts by



for "or" compound inequalties, solve each part separately:







Then





Multiply by -1. Since the multiplier is < 0, reverse the sense of the inequality:



Then state both parts with the "or"
