Which expression represents multiplying (x) by (-3) and then adding (8)?

Answer and explanation

Correct answer: -3x+8

Multiplying x by -3 gives -3x. Adding 8 afterwards gives the expression -3x+8. In option D, -3 multiplies both x and 8, producing -3x-24, so it is not correct. Exam tip: words such as “then adding” mean that the added number stays outside the multiplication.
