How did linear equations come into use? - Answers

Linear equations have been used for thousands of years, with their origins traced back to ancient civilizations like the Babylonians, who employed them for solving practical problems in trade and land measurement. The formalization of linear equations evolved through the contributions of Greek mathematicians, notably Euclid and Diophantus, who explored geometric interpretations. By the 17th century, with the advent of algebra, linear equations became more systematically studied, allowing for broader applications in various fields such as physics, engineering, and economics. Today, they are fundamental in mathematical modeling and problem-solving across disciplines.
