Question 43321
can someone please solve this one...
use Gauss-Jordan elimination and solve this
3x - y = 5
4x + 2 = 10

AUGMENTED MATRIX IS
3......-1.......5
4.......2.......10

NR1=R1/3

1......-1/3......5/3
4........2........10

NR2=R2-4*R1

1.......-1/3.............5/3
0.......2+4/3=10/3.......10-20/3=10/3

NR2=R2*3/10

1.......-1/3..............5/3
0.........1................1

NR1=R1+R2/3

1.............0............5/3+1/3=2
0.............1...............1

HENCE X=2
Y=1
