Solve the inequality \(|5x - 3| < 2|3x - 7|\).
Solution
To solve the inequality \(|5x - 3| < 2|3x - 7|\), we first consider the non-modular inequality:
\((5x - 3)^2 < 2^2(3x - 7)^2\).
This simplifies to:
\(11x^2 - 138x + 187 > 0\).
We solve the quadratic equation \(11x^2 - 138x + 187 = 0\) to find the critical values:
\(x = \frac{17}{11}\) and \(x = 11\).
The solution to the inequality is:
\(x < \frac{17}{11}\) or \(x > 11\).
