Solve: 3x>12-3x > 12

A

x<4x < -4

B

x>4x > -4

C

x<4x < 4

D

x>4x > 4

Correct Answer: A

Choice A is the correct answer. Remember to flip the inequality sign.

  1. Divide by -3: x<4x < -4
  2. Flip the sign: When dividing by a negative, the inequality reverses.

💡 Strategic Tip: Always flip the inequality when multiplying or dividing by a negative number.

Choice B is incorrect because it forgot to flip the sign. Choice C is incorrect because it has the wrong value. Choice D is incorrect because it has both wrong direction and wrong value.
