    16 decreased by 3 times the sum of 3 and a number

    Take this algebraic expression in parts:
    • The phrase a number means an arbitrary variable. Let's call it x.
    • The sum of 3 and a number: 3 + x
    • 3 times the sum: 3(3 + x)
    • 16 decreased by... means we subtract 3(3 + x) from 16

    3(3 + x) from 16
