Test x = 15: |3(15) - 5| = 40; 2(15) + 10 = 40. Matches immediately.
Case 1: \(3x - 5 = 2x + 10 \implies x = 15\). Check: \(|3(15) - 5| = |40| = 40\), and \(2(15) + 10 = 40\). Valid! Case 2: \(3x - 5 = -(2x + 10) = -2x - 10 \implies 5x = -5 \implies x = -1\) (negative solution). The positive solution is 15....
