Well heres the question:(adsbygoogle = window.adsbygoogle || []).push({});

Find 'X' where 'AX = '

6

8

4

and 'A = '

1 2 4

3 1 2

0 2 4

Now i would go ('AX')*('A^-1') which would clearly give me 'X' BUT 'A' is not invertible! So how do i do this? (by the way the ' is not part of the question).

And then it says find the null vectors of A and hence the general solution. what do i do here?
