    Step-by-step explanation:

    let the age of man be x

    400-3x=163

    Step-by-step explanation:

    Let x be the age of wise man

    3 time his age = 3x

    400 reduced by 3 times his age = 400 - 3x

    400 - 3x = 163

    -3x = 163 - 400

    -3x = - 237

    x = - 237/-3

    x = 79 years
