Who discovered the systems of linear equation?

Answer 1

The concept of systems of linear equations dates back to ancient civilizations such as Babylonians and Egyptians. However, the systematic study and formalization of solving systems of linear equations is attributed to the ancient Greek mathematician Euclid, who introduced the method of substitution and elimination in his work "Elements." Later mathematicians such as Gauss and Cramer made significant contributions to the theory and methods of solving systems of linear equations.

Answer 2

The history of linear algebra begins with Leibniz in 1693 who studied determinants. In 1750, Cramer invented a rule (Cramer's rule) for solving linear systems.
