Solve the inequality 3x - 4 > 11.
Answer and explanation
Correct answer: B. x > 5
- Step 1: Add 4 to both sides: 3x > 15. Step 2. Divide by 3: x > 5. Answer: x > 5. Why not the others: x > 3: That divides 11 by 3 without first adding the 4. x < 5: The direction of the inequality only reverses when multiplying or dividing by a negative number. x > 7: That adds 4 on the wrong side.
