Please answer this question using matrices. I sent it earlier today and it was soft but I think the answer was wrong. I was using Cramers rule and the inverse role to try to solve it and I just can't seem to get the right answer. I need to explain this to a student who is taking pre-calculus in high school so please don't solve it was very very advanced methods. Thank you so much
