    Number=x since unknon

    add 3 to x

    3+x, thenmultiply by 5

    (3+x) timmes 5 answer is 35

    5 (3+x) = 35

    now distribute useing distributive property

    a (b+c) = ab+ac

    5 (3+x) = 15+5x

    15+5x=35

    subtract 15 from both sides

    5x=20

    divide both sides by 5

    x=4

    the nuber is 4
