Answer:

14x + 30y -2z - 8

Step-by-step explanation:

13x + 17y - 19z + 2 + 14x + 12y - 31 + 12 - 15x + 6z + 2x + y + 11z + 9 = x(13+14-15+2) + y(17+12+1) + z(-19+6+11) +2-31+12+9 = 14x + 30y - 2z - 8

P.S.

I doubt whether in the second polynomial, that you wrote that 12x and 31 improperly. Not sure, though.
