hii
here is your solution
(13x+17y-15z+2)+(14x+12y-31)+(21-15x+6z)+(2x+y+11z+9)
→ (13x+14x-15x+2x)+(17y+12y+y)-(15z+6z+11z)+(2-31+21+9)
→13x+14x-15x+2x+17y+12y+y-15z-6z-11z+2-31+21+9
now calculate these expressions
first we will solve x variable
→13x+14x-15x+2x
→14x. [13x+2x=15x] [+15x-15x=0]
now we will solve y variable
→17y+12y+y
→30y
now solve z variable
→-15z-6z-11z
→-32z
now solve the numbers
→+2-31+21+9
→-29+30
→+1
now take all the variables and no.s
→14x+30y-32z+1
it is your solution
there is no need to solve every variable separately
I have done it just for your understanding.
hope it helps ❗❗
