heya mate
(( some not its sum )) ok now no issues
here is your answer
1stly add last 2 equations like this
(x - 3y + 2z) + (-4x + 9y - 11z)
=> x - 3y + 2z - 4x + 9y - 11z
=> -3x + 6y - 9z
now subtract 3x - 4y - 7z
from -3x + 6y - 9z
(-3x + 6y - 9z)-(3x - 4y - 7z)
-3x + 6y - 9z - 3x + 4y + 7z
= (-6x +10y - 2z)
