Solve: x/3 = 4.

## The reasoning This is a **basic algebraic equation** where we need to isolate x. Starting with: **x/3 = 4** To find x, we need to "undo" the division by 3. We do this by multiplying both sides by 3: **x/3 × 3 = 4 × 3** The 3s on the left cancel out: **x = 12** Think of it practically: "What number divided by 3 gives 4?" That's 12, because 12 ÷ 3 = 4. ## Why the wrong options tempt you **A) 7** — You might mistakenly add 3 to 4 instead of multiplying. Wrong operation! **C) 1** — Perhaps you divided 4 by 3 instead of multiplying. You went the wrong direction. **D) 4** — You might have confused x with the answer on the right side. Don't just copy what you see! ## Quick takeaway **To solve x/a = b, multiply both sides by a to get x = a × b.** Division problems need multiplication to solve them — they're inverse operations!
