Mathematics | L U Decomposition of a System of Linear Equations Last Updated: 02-04-2019 L U decomposition of a matrix is the factorization of a given square matrix into two triangular matrices, one upper triangular matrix and one lower triangular matrix, such that the product of these two matrices gives the original matrix. Most of the time, a systems of equations question on the ACT will involve two equations and two variables.It is by no means unheard of to have three or more equations and variables, but systems of equations are rare enough already and ones with more than two equations are even rarer than that. The equations relate to one another, and each can be solved only with the information that the other provides.
