To solve this absolute value inequality, we will consider two cases: when the expression inside the absolute value is positive and when it is negative.

Case 1: 4x-3 > 7
Adding 3 to both sides of the inequality, we get:
4x > 10
Dividing both sides by 4, we obtain:
x > 10/4
Simplifying the fraction, we get:
x > 5/2

Case 2: -(4x-3) > 7
Distributing the negative sign, we have:
-4x + 3 > 7
Subtracting 3 from both sides of the inequality, we get:
-4x > 4
Dividing both sides by -4 and reversing the inequality sign:
x < -1

Combining both cases, we find the solution to the inequality:
x < -1 OR x > 5/2
