Linear algebra is one of the fundamental mathematical tools widely applied across various fields of economics. This paper examines several practical applications of linear algebra in solving economic problems. In particular, it highlights the possibilities of analyzing data and determining optimal decisions through the modeling of economic processes using linear algebraic methods. The roles of key concepts - such as matrices, vectors, systems of linear equations, and determinants - in economic modeling and analysis are discussed. The results of the study substantiate the practical significance of linear algebra in economics and demonstrate its effectiveness in addressing complex economic problems.
