Hey,

Can someone please tell me how to know if an equation has no solution.....

cuz the question goes like:

3x- 4y = 10

6x+wy = 16

For which of the following values of w will the system of equations above have no solutions?

A)-8

B)-4

C)0

D)4

E)8

What should I do? Any attempt to help me would be very much appreciated (-:

Thanks
