To state: How to decide whether substitution is the best method to solve a system of equation in three variables.
If a variable can be solved easily from a given system of equation then it is better to use the substitution method.
Given information:
The given statement says to how to decide whether substitution is the best method to solve a system of equation in three variables.
Explanation:
Consider the below given statement:
If in a system of equations there are three variables and any one variable can be easily solved then the substitution method is best method to solve that system of equations.
Now consider the below given example:
It can be seen that in the above given system of equation it is better to use the substitution method because the first equation can be easily solved for the value of x variable.
