Question

Solve the given system of equation by Gauss Elimination method. 3x + 4y – z = -6 -2y + 10z = -8 4y – 2z = -2

plz fast ans
now start my test​

Answer 1

Step-by-step explanation:

the given equation can be resolved separately

1. 3x+4y-z=-2

2.-6-2y+10z=-2

3.-8+4y-2z=-2

multiply equation 2 by 2 and add equation 2 and 3

new eq 2 is

-6x2-2yx2 +10z x 2 = -2x2

-12-4y+20z=-4

now add equation 2 and 3

-12-4y+20z -8 +4y -2z= -2 -4

on solving

z=14/18

put the value of z in equation to and you will find the value of Y

similarly put the values of Y and z in the equation 1 and you will find the value of x and y equation thus will be solve
