This one is my favorite. Find c.
I first tried to solve this system of equations by working backward, substitute each answer into the system to see which answer works. I found the answer but it takes a while. This question can be easily solved by adding the second and third equations together:
The interesting discovery is that we can substitute (a+b) by 3 without knowing what a and b are. System of equations is a topic in Math 11, but it doesn't mean we need to wait til grade 11 to understand it.
