  • Question is incorrect in that there is no = sign in second equation.

    Will assume that it should be

    3x + 6y = – 2

    15x + 30y = – 10

    .

    Option c

  • 3x + 6y =- 2 ……………..(1)

    15x + 30y = -10………….(2)

    Divide (2) by 5

    3x + 6y = – 2…………..(3)

    Equations (1) and (3) are the same equation

    Hence , no solution. In other words the lines do not intersect
