Solve `|3x-2|=xdot`

Explanation

To solve the equation \( |3x - 2| = x \), we need to consider two cases due to the absolute value.

### Step 1: Set up the cases
The absolute value function can be defined in two cases:
1. \( 3x - 2 = x \) (Case 1: when the expression inside the absolute value is non-negative)
2. \( 3x - 2 = -x \) (Case 2: when the expression inside the absolute value is negative)

### Step 2: Solve Case 1
