Question

tìm x bít (x+1)+(x+2)+(x+3)+.........+(x+2017)=0

mk dag cần gấp giúp mk vs nha  thank nhìu

ai làm nhanh đúng mk tick mk hứa

 

Answer 1

(x+1)+( x+2)+(x+3)+.....+(x+2017) = 0

=> x+1+x+2+x+3+x+4+...+x+2017 = 0

=> (x+x+x+x+x+..+x )+ (1+2+3+4+...+2017 ) =0

=> 2017x + 2035153 = 0

=> 2017x = -2035153

=> x = -2035153 : 2017

=> x = -1009

Vậy x = -1009

Đúng thì k mk nha !!!!

Answer 2

100x*(1+2+3...+2017)=0

100x*2035153=0

100x=0/2035153

100x=0

x=0/100

x=0
