(if there is no solution, enter No souuTION. if the system has an infinite number of solutions, set x2 and solve for x1 in terms of t 1 o oExplanation / Answer
The elementary row operations being performed are:
On performing the 1st of these row operations, the 3rd row will change to the one shown in the 2nd ( row equivalent) matrix and on performing the 2nd of these row operations, the 2nd row will change to the one shown in the 2nd ( row equivalent) matrix .
The solution set for the system of linear equations represented by the given augmented matrix is 1 x1 + 0 x2 = 0 i.e. x1 = 0 and 0 x1 + 1 x2 = 3 i.e. x2 =3. The solution set is (x1, x2 )= (0,3)
