The EquationSolver is carefully designed to be a simple and elegant app. Easy to use, easy to understand, simple and effective It solves system of linear equations, simultaneous linear equations (no limit on the number of equations). It also teaches you the steps to solve such systems. To find a solution, it uses Matrix inversion method or LU decomposition method when inverse is not possible or complicated. The equations are beautifully presented in both: 1) Set of individual equations form 2) Matrix-vector product form. You can also share the beautifully written solution It automatically saves your hard work locally on your device so you can come back and pick up from where you left off as your great effort will not be lost. This is a perfect app if you are a student learning to solve these kind of equations. There is also a Study page to help you with learning some important linear algebra formulas.
