Solve the system, or show that it has no solution. If the system has infinitely many solutions,
express them in the ordered-pair form given in Example 6.
Hence, the solution of the system of equations has no solution hence inconsistent.
Given a system of equations
We are solving equation (1) for x,
We are substituting equation (3) in equation (2),
Adding on both sides,
Since, this is false so the system is inconsistent, i.e. no solution.
