Use the result matrix to declare the final solutions to the system of equations.
Since does not contain the variable to solve for, move it to the right side of the equation by adding to both sides.
Since does not contain the variable to solve for, move it to the right side of the equation by subtracting from both sides.
The solution is the set of ordered pairs that makes the system true.
There is not a transformation of the vector that exists because there was no unique solution to the system of equations. Since there is no linear transformation, the vector is not in the column space.
Not in the Column Space
