I competely forgot how to do Cramer’s Rule?
It was my first day of school and we got this sheet that’s supposed to be an Algebra II review (I’m in Analysis/Trig this year). Unfortunately, I have NO idea how to use Cramer’s Rule and I can’t seem to find my old notes on it. This is the problem I need to do.
4x + 5y – z = 7
2x – y + 3z = 7
x – 4y + 15z = 7
Can you walk me through this? I really don’t want just an answer. I need to be able to understand how to do it in the future.
