Choice Dhoice C is the correct answer. This multiplication equation requires division to solve.

1. Start with the equation: $4x = 28$
2. Divide both sides by 4: $x = \frac{28}{4}$
3. Simplify: $x = 7$
4. Verify: $4(7) = 28$ ✓

💡 Factor Approach: Notice that $28 = 4 \times 7$, so dividing 28 by 4 gives us 7.

Choice Dhoice C is incorrect because this results from subtracting: $28 - 4 = 24$. Subtraction is not the inverse of multiplication.

Choice Dhoice D is incorrect because this comes from adding: $28 + 4 = 32$. Addition doesn't undo multiplication either.

Choice Dhoice A is incorrect because this results from multiplying: $28 \times 4 = 112$. This compounds the multiplication instead of reversing it with division.
