#### Explanation

#### Explanation:

#### Answer:

#x<4# and in interval notation# x in(-oo,4)# #x<=-1# and in interval notation#x in(-oo,-1]#

#### Explanation:

Lets take the first example.

This is an inequality. Inequalities are usually solved like regular equations.

Lets add

Divide both sides by

This inequality means that the value of

In interval notation it will be written as

Similarly when we simplify

So here the interval notation is
