Given:

|x-5|+4&gt;0 ...(1)

|x^2|&lt;4 ...(2)

The mode inequality can be solved by isolation.

|x-5|+4&gt;0 ...(1)

|x-5|&gt;-4

The mode functions are positive or 0, so this has solutions over reals.

|x^2|&lt;4 ...(2)

-4&lt;x^2&lt;4

This gives two inequalities for x.

\displaystyle{\left \{ {{x^2&gt;-4} \atop {x^2&lt;4}} \right. }

The upper inequality has solutions over reals.

The inequality below gives -2 &lt;x&lt;2.

Solution

The intersection of three ranges is -2&lt;x&lt;2.

More information:

We usually find the ranges where the mode becomes 'negative', and '0 or positive'. When mode becomes negative, we apply a negative sign.

This fact is used in mode equations and inequalities.
