4. Solve |4x - 7| > 11 and write set notation for the solution set.

A.

B.

C.

D.

We know that |x|>a ==> either x< -a or x>a

Hence |4x - 7| > 11==> 4x-7< -11 or 4x-7 >11 i.e., 4x< -4 or 4x>18. ...

#### Solution Summary

Solution sets and interval notation are investigated. The solution is detailed and well presented.
