Which of the following matrices represents the system of equ

Which of the following matrices represents the system of equation given by: 2x+3y+4z=5 x-12y+7=6z 8z+9y+10x=13

Solution

here 2x+3y+4z=5

x-12y+7=6z

or x-12y-6z=-7

8z+9y+10x=13

or 10x+9y+8z=13

thus the matrices represent the system of equation is

2 3 4 5

[ 1 -12 -6 -7

10 9 8 13

thus the fourth option is correct
