-5 < 4x - 4 < -3

Add +4 to all three sides:

-5 < 4x - 4 < -3
+4      + 4   +4
----------------
-1 < 4x     <  1

Next divide all three sides by the coefficient of x,
which is 4,

{{{(-1)/4 < (4x)/4     <  1/4}}}

or, canceling 4's,

{{{(-1)/4 < (cross(4)x)/cross(4)     <  1/4}}}

or

{{{(-1)/4 < x     <  1/4}}}

That's called the solution.

The solution set is

{{{"{x|"}}}{{{-1/4<x<1/4}}}{{{"}"}}}
