To describe: the error.
Answer to Problem 102E
A solution of the system
A solution of the system
Explanation of Solution
Given information: A solution of the system
Calculation:
The given system is,
The solution of given system is (3,0,-1) means all three equation must satisfies (3,0,-1).
So (3,0,-1) is not the solution of the given system of linear equation this is the error.
To find the solution of the given system, adding equation 2 and equation 3.
Substitute the value of x=5/2 in equation 1 and 2.
So, the solution of the given system of linear equation is (5/2, 3/4, 1/4) and (3, 0, -1) is not the solution of the given system.
If change the third linear equation as
So, A solution of the system
A solution of the system
