How did linear equations came into use? - Answers

Linear equations emerged from the need to solve practical problems involving relationships between quantities. Ancient civilizations, such as the Babylonians and Egyptians, used simple algebraic methods to solve problems related to trade, land measurement, and construction. Over time, mathematical frameworks were developed, leading to the formalization of linear equations in the context of algebra during the Middle Ages and the Renaissance, as scholars sought to represent and manipulate these relationships more systematically. This evolution laid the groundwork for modern algebra and its applications in various fields.
