Choosing substitution instead of elimination can feel tricky and overwhelming at times. But there are certain situations where using substitution might be a better choice. Here are some examples:
Easier to Solve for a Variable: If one equation has a variable that is easy to express using the other equation, substitution might seem like a good idea. However, this can lead to complicated fractions.
Boring Repetitive Work: If substituting causes a lot of tedious math work, it can be easy to make mistakes. That's when elimination might be the easier route to take.
Weird Answers: Sometimes, equations can give answers that are not whole numbers or are fractions. In these cases, substitution might become a hassle compared to elimination.
Even though there are challenges, you can make substitution work for you! Just stay organized and double-check each step to ensure it's correct. By keeping a clear method, even students can tackle these challenges successfully.
