I don't see how you found the numerators to be -58; I calculated them to be -4. Please show your work.

What rule did you apply? Cramer's Rule or Calculator Rule???

Awesome video. Thank you! Thanks for showing the correct answers. I found where I made a mistake with my gaussian elimination.

[ryanvales]

Are you solving? Even one line, I didn't see
