Solve the inequality: \(|2x - 5| > 3|2x + 1|\)
Solution
To solve the inequality \(|2x - 5| > 3|2x + 1|\), we consider two cases based on the definition of absolute value.
Case 1: \(2x - 5 > 3(2x + 1)\)
Simplifying, we get:
\(2x - 5 > 6x + 3\)
\(-5 - 3 > 6x - 2x\)
\(-8 > 4x\)
\(x < -2\)
Case 2: \(2x - 5 < -3(2x + 1)\)
Simplifying, we get:
\(2x - 5 < -6x - 3\)
\(2x + 6x < -3 + 5\)
\(8x < 2\)
\(x < \frac{1}{4}\)
Combining both cases, the solution is \(-2 < x < \frac{1}{4}\).
