Nine less than a number is no more than 8 and is no less than 3.
compound inequalities

For this case what we must do is find the compound inequality.

To do this, we must first define a variable.

We have then:

x: unknown number.

We write the inequations now:

Therefore, the compound inequation is:

The solution of the inequality is:

Inecucción 1:

Inequality 2:

Then, the solution is:

x ∈ [12, 17]

The compound inequation is:

The solution is:

x ∈ [12, 17]
