To solve the equation \( |2x - 1| = 3[x] + 2\{x\} \), where \([x]\) is the integral part of \(x\) and \(\{x\}\) is the fractional part of \(x\), we will break it down into two cases based on the definition of the absolute value. ### Step 1: Define the Cases The absolute value function \( |2x - 1| \) leads us to two cases: 1. Case 1: \( 2x - 1 \geq 0 \) (i.e., \( x \geq \frac{1}{2} \)) 2. Case 2: \( 2x - 1 < 0 \) (i.e., \( x < \frac{1}{2} \)) ### Step 2: Solve Case 1 ...
