Solve 4x = 24.

**The reasoning** This is a simple linear equation. To find x, we need to isolate it on one side. We have: 4x = 24 Divide both sides by 4: x = 24 ÷ 4 = 6 **The principle:** When solving equations, perform the inverse operation to isolate the variable. Since x is being multiplied by 4, we divide by 4 to "undo" it. **Why the wrong options tempt you** - **Option A (4):** You might confuse the coefficient with the answer itself. Don't just pick the number you see attached to x! - **Option C (8):** This comes from subtracting instead of dividing (24 − 16 = 8). Wrong operation! - **Option D (10):** Perhaps from faulty mental math or adding instead of dividing. **Quick takeaway** Whatever operation is happening to x, do the opposite to both sides — multiplication becomes division, addition becomes subtraction, and so on. Practice this "inverse thinking" and you'll never miss these again! 💪
