Solve Inequality |7x+3| > 15. What are the steps to putting my answer(s) in interval form?


Expert Answer

Step 1

From |7x+3|>15 we get two inequalities. 7x+3>15 and 7x+3<-15. We will solve for x from those two inequalities. 

Step 2

From 7x+3>15 we get x>12/7.  It can be written as (12/7, infinity).

Step 3

From 7x+3<-15 we get x<-18/7.  It...
