How will you write subtracting 7 from 4 times s?

Answer and explanation

Correct answer: 4s − 7

The governing skill is translating a verbal statement into an algebraic expression while preserving the order indicated by the language. “Four times s” means 4s. The phrase “subtracting 7 from four times s” means that 4s is the starting quantity and 7 is removed from it, giving 4s − 7. Therefore option B is correct. Option A changes subtraction into addition. Option C reverses the order and represents 7 − 4s, which means subtracting 4s from 7. Option D incorrectly changes the multiplication into a different subtraction and does not contain the required term 4s. Careful attention to the word “from” prevents the common reversal error.
