To solve the following system of linear equations
Answer to Problem 2AGP
No Solution
Explanation of Solution
Given:
Concept used:
System of linear equations can be solved using inverse matrix method.
To find inverse of a square matrix A, following steps should be followed.
- Augment given matrix with the identity matrix
- Perform row operations to make the identity matrix to the left and the right matrix becomes inverse matrix.
In this way, inverse matrix of a matrix can be obtained.
Formula used:
Calculation:
Consider given system of equations,
Writing above system of linear equations in matrix form
Here,
Now, find the inverse matrix of matrix A.
Step 1: Augmenting matrix A with the identity matrix
Step 2: Performing row operations to make the identity matrix to the left.
Since the second row contains solely zero, the determinant of the matrix is zero.
So, matrix is not invertible ,
Finding the solutions,
Since there is no possible inverse of the given matrix, hence there can be no possible solution of the given system of equations.
Conclusion:
Therefore, the there is no solution to the given system of equations.
