This week, I learned about which method I should use to solve systems, an example is…

before we decide which method to use, we have to determine what situations we would use each of the methods, now, there is actually a third method where we can graph it, but its the hardest and most ineffective way in my opinion and these two are the best and most effective to use. an example with systems is…

On our first example, we can see that their is no isolated variable and once we see that, we automatically look towards elimination, which checks all the boxes which means elimination would be the best strategy.

In this example, we can see that their is an isolated variable so right off that we can see that substitution would be the best method, and although Elimination could be used for every system, it would be much easier to use substitution when there is an isolated variable.
