Solve the equations and graph the solution

Given:

The inequalities are:

or

To find:

The solution for the given inequalities and graph the solution.

Solution:

We have,

or

Solve the above inequalities separately.

Divide both sides by -5.

            ...(i)

And,

Divide both sides by 2.

                      ...(ii)

From (i) and (ii). we get

or

The interval notation of the solution is .

The graph of the solution is shown below.
