How can I find $\displaystyle $t$$ for system of linear equations, that the system would not be solvable?
I tryed with this code:
Code:x = 10 y = 10 z = 10 Solve[{ 9 x - 8 y + t*z == 1, 6 x - 8 y - 5 z == 1, 3 x -7 y + 9 z == 1}, {t}]

You have a highly over-determined system there. There are no solutions. Think about it:
90-80+10t=1
60-80-50=1
30-70+90=1
Some of those equations are downright incorrect. I would review your steps for arriving at that system of equations. What's the bigger context for this problem?
Whoops. That approach won't work. Take a look at this thread. Make sure you scroll all the way down to the end to get the real reason why that works.
