Use the result matrix to declare the final solutions to the system of equations.
The solution is the set of ordered pairs that makes the system true.
Decompose a solution vector by re-arranging each equation represented in the row-reduced form of the augmented matrix by solving for the dependent variable in each row yields the vector equality.
