Video Description: ============================================================ In this session Jim demonstrates how to solve equations simultaneously using a combination of approaches including inverse matrix operations, the linsolve command, row reduction (manually) and row reduction in Echelon form (automatic). Interpretation of the results is also covered including solutions in 3 dimensional space (3 variables).
