Using systems of linear equations to solve unknowns was formalized. Other efforts from scholars like cayley, euler, sylvester, and others changed linear systems into the use of matrices to represent them. Gauss brought his theory to solve systems of equations proving to be the most effective basis for solving unknowns.

Patience is hard to come by, which is why physicists and engineers love to use linear algebra – no one wants to solve a circuit with over four variables. When using kirchoff’s laws to create equations and solve, using matrices and gaussian elimination helps to simplify the solutions.
Solving currents in a circuit (7 × 7 system) we solve this using a computer as follows. We just write the coefficient matrix on the left, find the inverse (raise the matrix to the power -1) and multiply the result by the constant matrix.
