    i just solve it in my notebook and telling answers i am not guessing if u want answer i can type the whole thing. this is the answer : switch like terms next to each other (2x - 2y + 5z - 2x - y + 3z) change to ( 2x - 2x + y - 2y - 5z + 3z) next the y thats all alone add one in front of it.. thats just saying that theres only one y add/subtract like terms 2x - 2x = 0, 1y - 2y = 1y, 5z + 3z = 8z so you'll have ( 0 + 1y - 8z) leave the zero and youll answer : 1y - 8z

    1st 1y - 2y = 1y is incorrect to begin with; correction: 1y - 2y = -1y however the correct one is -1y - 2y = -3y all 3 people how gave you medal dont know math at all

    @katragaddasaichandra can you just look at the problem again and to your answer you said (2x - 2y + 5z - 2x - y + 3z) change to ( 2x - 2x + y - 2y - 5z + 3z) 1. why do we have -y change to +y and +5z to -5z? 2. 2x - 2x = 0, 1y - 2y = 1y, 5z + 3z = 8z 1y - 2y = -1y; you said step earlier its -5z+3z so that should be -2z 3. ( 0 + 1y - 8z) in step two you said it was +8z, how did it change to negaive 3.
