In this note, we demonstrate with illustrations two different ways that MS Excel can be used to solve Linear Systems of Equation, Linear Programming Problems, and Matrix Inversion Problems. The advantage of using MS Excel is its availability and transparency (the user is responsible for most of ...
A System of Linear Equation (SLE) that has the same number of equations as the number of variables is called the Determined SLE. But, an SLE with non-integer solutions is a problem for students. This paper can assist teachers in providing exercises on the topic of SPL with integer solution...

There is no equation such as 0 = 1, so the existence of a solution is already clear. Also the solution is not unique because there are free variables. ;Using Row Reduction to Solve A Linear System 1: Write the augmented matrix of the system. 2: Use the row reduction algorithm to ...
Property 1: If A is a square matrix (i.e. the number of equations is equal to the number of unknowns), the equation AX = C has a unique solution if and only if A is invertible (i.e. det A≠ 0), and in this case, the unique solution is given by X = A–1C. Proof: Supp...
