    Twenty less

    -20

    than four times a certain number

    4x

    is

    = 4.

    4x - 20 = 4

    4x = 24

    x = 6

    Alternatively, work it backwards:

    Starting with 4, working backwards twenty less = twenty more

    20 + 4 = 24

    If four times a number = 24, the answer must be 6.

    If 4x -20 = 4 then x = 6

    You can just trial and error, I first tried 4 which would get -4, then I tried 5 which would get you 0, then I got six as 4!
