Question 145141: I would really appreciate some help on a few questions please.These are on the cramers rule 3 x 3:
1)3x + y + 2z = 3
x - 5y - z = 0
2x + 3y + 2z = 0
2)x - 3y + z = 7
x + y - 3z = -9
x + y + z = 3
Thank you for your time and patients LJ

You can put this solution on YOUR website!
You have posted a number of problems.
Are you looking for the answers or the process?
Illustrating the manipulation of determinants is a messy
business. Maybe using Google you can find examples of
the process for solving systems of equations.
