Question

0-1 Solve the following systems of equations
if possible :
i) 2x-3y-z=3 , x+2y-z=4 , 5x-4y-3z=-2
by Gauss elimination method​

Answer 1

Answer:

ggff+53+(&$7-_77_+909')

Answer 2

Answer:

Solutions

x+y=5 −(1)

2x−3y=4 −(2)

Multiplying eqn (1) with 3 and adding to eqn (2)−

3x+3y=15

+ 2x−3y=4

__________________

5x+0y=19

∴x=

5

19

=3.8

Substituting in eqn (1)−

y=5−x=5−3.8=1.2

∴x=3.8,y=1.2
