These are the equations of 3 lines in 3 dimensions.

Alan and Aziz have discovered that there is no point that all 3 of these lines go through.

The lines are not "concurrent".

These are a system of equations, rosala. The three points should satisfy all 3 equations: (x,y,z).

You are right, anonymous. There is no solution.

Subtract the second equation from the first and you get:

x - 5y - 3z = 2

 

But the third equation says that

x - 5y - 3z = 5

 

They can't both be true at the same time, hence there is no solution!
