Math 10 – Week 15

Solving Systems, But Better

Using a graph for salving more complex systems kinda sucks, so you’ll need to find another way to solve those juicy systems.

Well let my introduce the best way to solve systems, elimination!

 

So when you have a system, you can add them together. when you add them together (make sure the x or y can equal 0)(also can multiply/divide an equation to get it good) it’ll make the system into 1 single equation, where if you find the value for x or y (in the example, is x), you can also find the other missing value by imputing the newly discovered value into one of the system’s equations.

In the example above, there is a lot of tedious math (mainly because I accidentally made it this way) and make sure you verify your answer to ensure that the answer is correct.
