Do we solve it using determinants or gaussian elimination?

GAUSSIAN ELIMINATION

n the Gauss elimination method for solving a system of linear algebraic equations, triangularization leads toa)Upper triangular matrixb)Lower triangular matrixc)Singular matrixd)Diagonal matrix

A use Gauss-Jordan elimination (with no row exchanges) to find A−1.

Apply elementary operations of linear system, solve the following system of linear equations.State your steps clearly. (hint: please use Gaussian elimination when conducting row opera-tions)(a)2x1 + 3x2 = 24x1 − 5x2 = 15(b)x1 + x2 − x3 = 62x1 + 4x2 + 5x3 = 113x1 + 4x2 + 10x3 = 8

Solve the system by using Gaussian elimination or Gauss-Jordan elimination.+2x7y = −15+x4y = −11
