Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities

Answer 2

Answer:

(x+3y−4z)+(2x+y−z)+(−2x+3y−z)−(2x−4y+3z)

=(x+2x+3y+y−4z−z)+(−2x+3y−z)−(2z−4y+3z)

=(3x+4y−5z)+(−2x+3y−z)−(2x−4y+3z)

=(x+7y−6z)−(2x−4y+3z)

=x−2x+7y+4y−6z−3z

=−x+11y−9z

∴ Ans is (−x+11y−9z)
