Wolfram|Alpha is capable of solving a wide variety of systems of equations. Prepare an Augmented Matrix of 4 rows and 5 columns.Įach row in the Augmented Matrix will represent one of the four equations.Equation 4: Compute A powerful tool for finding solutions to systems of equations and constraints Once the Augmented Matrix has been converted to triangular form, the solution to every variable can often be read directly from the matrix with no further work.įirst, arrange all three equations in standard form. The following method is illustrated below: (1) preparing an Augmented Matrix, and then (2) using row operations to convert the Augmented Matrix into a triangular form. There are several ways of solving this system of equations. Do not use mixed numbers in your answer.) If the system is dependent, set w = a and solve for x, y and z in terms of a. (If there is no solution, enter NO SOLUTION. Solve the system of linear equations and check any solution algebraically. For this reason I RECOMMEND USING A CALCULATOR. There are MANY CALCULATIONS involved, which means there is a high probability of making errors in arithmetic. Replace any row with the result of adding that row to another row. multiply any row by a number which is not zeroģ. To convert the convert the Augmented Matrix to a triangular form, the following operations can be used:Ģ. To convert the augmented matrix into a triangular matrix, you can perform various row operations, one at a time. Once you have converted the matrix into the triangular form, the ? shown in row 1 will be the solution value of x, the ? shown in row 2 will be the solution value of y, and the ? shown in row 3 will be the solution value of z, and the ? in row 4 will be the value of w. The triangular form will look like this: a diagonal pattern of 1’s with 0’s everywhere else but the last column. THIS IS the GOAL: Convert the Augmented Matrix into a triangular form.
