To Find: The solution of the system of linear equation and check the solution algebraically
Answer to Problem 31E
every ordered triple of the form
Explanation of Solution
Given information: The given system of three linear equations in three variables
Concept used:Gaussian Elimination is the process of using valid row operations on a matrix until it is in reduced row echelon form
Calculation:
Adding the first equation to -3 times the second equation
____________________.
Adding the first equation to -3 times the second equation produces a new second equation
Adding -5 times the first equation and 3 times the third equation
______________________.
Adding -5 times the first equation and 3 times the third equation produces a new third equation
Adding -1 times the second equation to the third equation
________________________.
Adding -1 times the second equation to the third equation produces a new third equation
Let
so, every ordered triple of the form
