    Answer:

    3xy=14-2=12

    xy=12/3

    Xy=4

    9xy=2-6=-4

    xy=-4/9

    Xy= -0.44444

    Step-by-step explanation:

    Firstly we require the value of anyone variable

    3x=14-2y

    x=(14-2y)/3 substitute this value in another equation.

    so now,

    9x+6y=2

    \frac{9(14 - 2y)}{3}  + 6y = 2

    42 - 6y + 6y = 2

    42 > 2

    so here we can’t find the value of variable.

    so we can say that no value can satisfy both the equation.
