Question 392771: Please help! I need to solve the following using Cramer's Rule. The textbook doesn't do a good job of defining this, so i would be extremely grateful for any help!!
solve by Cramer's Rule:
3x=7y+1
2x=3y-1


solve by Cramer's rule:
x-3y+z=-2
x+2y =8
2x-y =1

Thank you for your help!
