Solve the inequality: 3x - 4 < 5x + 6.
Answer and explanation
Correct answer: C. x > -5
- Step 1: Subtract 3x from both sides: -4 < 2x + 6. Subtract 6: -10 < 2x. Step 2. Divide both sides by 2: -5 < x, which is rewritten as x > -5. Answer: x > -5. Why not the others: x < -5 reverses the inequality direction incorrectly; x > 5 and x < 5 arise from sign errors when adding 6.
