Answer:

Step-by-step explanation:

[tex]|4x - 7|[/tex] ≤ [tex]9[/tex]

With this, we can construct two inequalities:

[tex]4x - 7[/tex] ≤ [tex]9[/tex]

[tex]4x - 7[/tex] ≥ [tex]-9[/tex]

Solving for each one will give us the answer:

[tex]4x - 7[/tex] ≤ [tex]9[/tex]

[tex]4x[/tex] ≤ [tex]16[/tex]

[tex]x[/tex] ≤ [tex]4[/tex]

[tex]4x - 7[/tex] ≥ [tex]-9[/tex]

[tex]4x[/tex] ≥ [tex]-2[/tex]

[tex]x[/tex] ≥ [tex]\frac{-1}{2}[/tex]

This give us the following range:

[tex]\frac{-1}{2}[/tex] ≤ [tex]x[/tex] ≤ [tex]4[/tex]
