Weba) a. System of two linear equations with a unique solution: 2x + 3y = 11 4x - 5y = -3 To solve this system using Gaussian elimination, we can start by writing the augmented matrix: [2 3 11] [4 -5 -3] We can then use elementary row operations to transform this matrix into row echelon form: [2 3 11] [0 -17 -47] Finally, we can use back-substitution to solve … WebMay 30, 2013 · Thus, the fact that there is at least one nontrivial solution (other than the trivial solution consisting of the zero vector) implies that there are infinitely many solutions.
