    Step-by-step explanation:

    Let current age of father be y

    Therefore age after 2 years = y+2

    Let age of son be x

    By given condition,

    y+2=3x+8

    therefore,

    2-8=3x-y

    3x-y= -6

    let us assume x= -3,

    3x-y= -6

    3(-3)-y= -6

    -9-y= -6

    -y= -6+9

    -y=3

    y= -3

    let us assume x=3

    3x-y = -6

    3(3)-y= -6

    9-y = -6

    -y = -6-9

    -y = -15

    y=15

    let us assume x= 1

    3x-y = -6

    3(1)-y= -6

    3-y= -6

    -y = -6-3

    -y = -9

    y=9

    Ans. Solutions for given equation are (x,y) = (-3,-3), (3,15) & (1,9)
