4: Step-by-Step Solution and Graph

Translation:

' (3-x)/4 - 1 < (3x-1)/4 '.

To eliminate the denominators, multiply both sides by 4, yielding:

' 3-x-4 < 3x-1 '.

Rearranging the terms, we get:

' -x-3x < -1-3+4 '.

Combining like terms, we have:

' -4x < 0 '.

Normalizing the coefficient to 1, we get:

' x > 0 '.

Represent the solution set of this inequality on a number line, as shown in the graph.
