  1. Answer:

    9

    Step-by-step explanation:

    Given,

    3X-Y=3 ———–(1)

    9X-3Y=9 ———(2)

    so,

    Y=3X-3. —–(3) [ From 1st equation]

    by substituting the equ.(3)in equ.(2)

    = 9X-3(3X-3)

    = 9X -9X+9

    = 0+9

    = 9

    So, the answer is 9.

    I think it’s helpful for you..
