Open-Ended Write a system for which using the elimination method to solve the system is easier than the substitution method. Explain.
To state:Using the elimination method to solve the system.
Answer to Problem 13P
The system is:
Explanation of Solution
The elimination method is simpler than the replacement solution for statistical systems. The termination method is so called because the actual system is replaced (if necessary) by an equal system, where the addition of these two numbers removes one variable.
Example: - (a system ideally suited to the elimination method.)
According to question,
Since, Notice that there is a3x in the first equation and a-3x in the second equation. Adding the two equations elimination the variable x.
(Since, substitute this value of y back into either original equation (preferably, a simple one) and solve for x.)
The unique solution is the order pair
