please help, I have been unable to make any sense from this set of linear equations. Does this mean there is no solution?
x-2y+z=0
2y-8z=8
-4x+5y+9z=-9

I can only seem to get it to a point for example x=6-27z etc. No constant/real number value for any variable.

you need to graph the lines :D

irishboy123 · Answer

use the second one to get rid of the y's

and make 2 equations in x and z
