Explanation of Solution
Given:
Explain when it is better to solve an equation using algebraic methods and when it is better to solve by graphing.
Concept Used:
Algebraic method is better to use when the solution is not a whole number.
When the solution is not a whole number it is hard to determine the solution by graphing.
The advantage of solving linear equation by graphing is that it is relatively easy to do and requires very little algebra.
The main disadvantage is that your answer will be approximate due to having to read the answer from a graph. Where the solution is an integer values, this might be alright, but if you are looking for an accurate decimal answer, this might not be able to be achieved.
Another disadvantage to solving linear equations by graphing is that at most you can have two unknown variables (assuming that you are drawing the graph by hand).
Thus, algebraic method is better to use when the solution is not a whole number.When the solution is not a whole number it is hard to determine the solution by graphing.
