whether the two system of linear equation yield same solution and if so find the solution of system of linear equations.
Answer to Problem 79E
Two system of linear equations yield the same solution and the solution of the two system of linear equation is
Explanation of Solution
Given information: Two system of linear equations
(a)
(b)
Concept used:Gaussian Elimination is the process of using valid row operations on a matrix until it is in reduced row echelon form
Calculation:
The solution of the two system of linear equation is:
(a)
From equation 3 the value of
Finally, substitute
The solution of a is
The solution of second system is:
(b)
From equation 3 the value of
Finally, substitute
The solution of a is
Hence,
Two system of linear equations yield the different solution and the solution of the first system of linear equation is
