Determining Whether a System of Linear Equations Is Inconsistent
1- Is getting a false equation during the normal process of solving a system of linear equations (e.g. substitution/elimination) is the only way we ensure this system has no solutions?
2- If no, what other ways available?

If we have two equations A = B and A = C where B C, then we also know the system is inconsistent, for example.

Would you count gaussian (aka row) elimination as a possibility? Then there's no solution iff you get a row of zeros except a nonzero at the far right in the augmented matrix that you're doing row elimination on.

You have three numbers. The sum of these numbers are 7.2. The second number is twice as large as the first one. The third number is three times as large as the first one.
This is easily solveable by setting up an equation system such as:
a + b + c = 7.2
b = 2 a
c = 3 a
