Which is the number line solution of (6-4x<2x+24)?

Answer and explanation

Correct answer: (x>-3), open dot at (-3) shaded right

The direct answer is option A: x>-3, with an open dot at -3 and shading to the right. Solve step by step: 6-4x<2x+24. Subtract 6 from both sides: -4x<2x+18. Subtract 2x: -6x<18. Dividing by -6 reverses the inequality sign, giving x>-3. Because the inequality is strict, -3 is not included, so the dot is open; values greater than -3 lie to the right. Option B has the wrong direction. Option C uses a closed dot and includes -3, which is not allowed. Option D has both the wrong inclusion and the wrong direction. Checking x=0 confirms the result: 6<24 is true, and 0 lies right of -3. Common mistake: always reverse the sign when dividing or multiplying by a negative number.
