Answer:
x=-224/229,
y=296/229,
z=118/229
Step-by-step explanation:
-5x-7y-4z=-6
6x+2y+3z=-2
-x+2y-7z=0...........( multiple with (-5) and sum with 1st equation, mult with 6 and sum with 2nd equation)
______________
-x+2y-7z=0
-17y+31z=-6.....(mult with 14)
14y-39z=-2.....(mult with -17) then sum
___________
-x+2y-7z=0
-229z=-118, so here we have z=118/229.
14y-39*(118/229)=-2, from here we have y=296/229
-x+2*(296/229)-7*(118/229)=0, we get that x=-234/229
In the same way you can do this in the matrix form>>
