Matrix Inversion and Linear Systems

This video tutorial on the Civil Learning Online channel explains the matrix inversion method, a direct approach to solving linear equations. The tutorial covers the formulation of equations in matrix form, finding the determinant and inverse of a matrix, and solving for variables X, Y, and Z. The process involves calculating cofactors, transposing matrices, and performing vector multiplication to arrive at the solution. The video concludes with the final values of the variables and encourages viewers to engage with the channel for more content.
