Can't figure this math problem out:

Write an algebraic expression for the product of five less than a number and three, less eight, is twenty-eight.

HELP ME PLEASE!!

  • 6th grade math -

    Product is the answer of a multiplication problem.

    3(n - 5) - 8 = 28

    3n - 15 - 8 = 28

    3n = 28 + 23

    3n = 51

    n = 17
