Use the Gauss-Jordan method to solve each system of equations. For systems in three variables with infinitely many solutions, give the solution with a z arbitrary; for any such equations with four variables, let w be the arbitrary variable.
I have three of these problems and do not understand how to begin with them. if anyone can offer some assistance it would be greatly appreciated.
16. x+ 2y =5
2x +y =-2
18. 2x- 3y = 10
2x +2y = 5
20. 2x - 5y - 10 = 0
3x + y - 15 = 0
