    x ... third number

    4x ... second number

    x-9 ... first number

    (x) + (4x) + (x-9) = 141

    x+4x+x-9=141

    6x-9=141

    Let's add 9 to both sides ...

    9+6x-9=141+9

    6x=150

    Let's divide both sides by 6 ...

    (6x) / 6=150/6

    x=25

    third number ... 25

    second number ... (4) (25) = 100

    first number ... (25-9) = 16

    Let's check our work ...

    25+100+16=141

    141=141
