I have these 3 vectors. And I have to prove that they are dependent.(adsbygoogle = window.adsbygoogle || []).push({});

a=(-1,7,-4)

b=(3,5,-6)

a=(15,-1,-12)

I have tried to make 3 equtations with 3 unknows and the solve it. But I just get that the constants should be 0, what they should not be in order to prove they are dependent?
