Which expression represents subtracting (2) from three times a number (r)?

Answer and explanation

Correct answer: 3r-2

Three times the number r is 3r. Subtracting 2 from this result gives 3r-2. The option r-6 means subtracting 6 from r, so it does not represent the statement. Exam tip: In “subtract ... from ...”, write the quantity being subtracted after a minus sign.
