In this lecture, you are going to learn how to apply your knowledge of matrices in order to solve systems of equations. A system of equations can be written in a matrix form which makes it a matrix equation, and the matrix equation consists of three matrices. The first matrix is formed by the coefficients of x and y, the second matrix is formed by constants, and the third matrix is formed by the variables or the unknowns. Depending on whether the matrix of coefficients has an inverse or not, we can conclude if the system has any solutions or not. You'll learn more about this in the lecture.
*These practice questions are only helpful when you work on them offline on a piece of paper and then use the solution steps function to check your answer.
