Solve the system of linear equations also check any solution algebraically.
Answer to Problem 10CT
Explanation of Solution
Given:
Consider the system of equations
This system can be solved by using roe operations as shown below
Multiply the second equation by 3 and add it to the first equation to produce a new second equation;
Now the system with new second equation is
Multiply the second equation by −3 and add it to the first equation to produce a new third equation
Now the system with new third equation is
Multiply the second equation by −1 and add it to the third equation to produce a new third equation
Here 0=−21 is not a true statement, this system has no solution.
