  1. Answer:

    hey here is your answer

    pls mark it as brainliest

    so here we go

    Step-by-step explanation:

    now according to first case

    x=2(y-3)

    so x=2y-6 (1)

    now according to first condition

    x-y=3 (2)

    substitute value of x in (2)

    we get 2y-y-6=3

    so y=9

    substitute value of y in any of two equations

    we get x=12

    hence option b is ryt ie x is 12 years old presently
