Question
Chapter 6.4, Problem 20PPE
To determine
To decide: The method which will be best suitable to solve the given system of linear equations.
Expert Solution & Answer
Answer to Problem 20PPE
Elimination method
Explanation of Solution
Given information:
The equations
Concept Used:
- Substitution method is best suitable when either ofvariables can be expressed easily in terms of other variable using one equation.
- Elimination method is best suitable when any one of variable term can be cancelled out easily by simple addition or subtraction of equations.
- Graphing is best when the system of equations is complex to solve and when both of above two methods fails will result in a complicated process.
Explanation:
Since, in the given system of linear equations value first terms i.e. 3m can be cancelled out easilyusing subtraction. Therefore it is best to use the elimination method to solve these set of equations.
