There are a lot of methods to do this, i will discuss 2 of them, which i think they are the best, and the simplest. To make it easy to understand, let's solve these 3 equations as an example side by side with explaining the method, -----...
Systems of linear equations (or linear systems as they are called sometimes) are defined as collections of linear equations that use the same set of variables. That means that within systems of linear equations you have two or more linear equations with the same variables. This is an example of such a system:
Oct 27, 2020 · Cramer’s rule: In linear algebra, Cramer’s rule is an explicit formula for the solution of a system of linear equations with as many equations as unknown variables.It expresses the solution in terms of the determinants of the coefficient matrix and of matrices obtained from it by replacing one column by the column vector of the right-hand-sides of the equations.

Using the Matrix Calculator we get this: (I left the 1/determinant outside the matrix to make the numbers simpler) Then multiply A-1 by B (we can use the Matrix Calculator again): And we are done! The solution is: x = 5, y = 3, z = −2. Just like on the Systems of Linear Equations page.
This 3 equations 3 unknown variables solver computes the output value of the variables X and Y with respect to the input values of X, Y and Z coefficients. In mathematic calculations, there are many situation arises where the usage of equation containing 3 unknown variables need to be solved prior to go further with the calculations.
