Question

( x + 1 ) + ( x + 2 ) + ( x + 3 ) + ... + ( x + 100 ) = 5050

Answer 1

( x + 1 ) + ( x + 2 ) + ( x + 3 ) + ... + ( x + 100 ) = 5050

100x + 101.100 : 2 = 5050

100x + 5050 = 5050

100x = 0

x = 0

Answer 2

(x + 1) + (x + 2) + (x + 3) + ... + (x + 100) = 5050

(x + x + x + ... + x) + (1 + 2 + 3 + ... + 100) = 5050

      100 số x

100.x + (1 + 100).100:2 = 5050

100.x + 101.50 = 5050

100.x + 5050 = 5050

=> 100.x = 0

=> x = 0

Answer 3

\(\text{( x + 1 ) + ( x + 2 ) + ( x + 3 ) + ... + ( x + 100 ) = 5050 }\)

\(x+\left(100+1\right)\cdot100:2=5050\)

\(x+5050=5050\)

\(\Rightarrow x=0\)

Answer 4

Ta có:( x + 1 ) + ( x + 2 ) + ( x + 3 ) + ... + ( x + 100 ) = 5050

<=> (x + x + x + .....+ x) + ...... + (1 + 2 + 3 + ..... + 100) = 5050

<=> 100x + 5050 = 5050

=> 100x = 0

=> x = 0

 

Answer 5

\(\left(x+1\right)+\left(x+2\right)+\left(x+3\right)+.....+\left(x+100\right)=5050\)

\(=100x\left(1+100\right).100:2=5050\)

\(=100x+101.50=5050\)

\(\Rightarrow100x=0\)

\(\Rightarrow x=0\)

Answer 6

( x + 1 ) + ( x + 2 ) + ( x + 3 ) + ... + ( x + 100 ) = 5050

( x + x + x + ... + x ) + ( 1 + 2 + 3 + ... + 100 ) = 5050

x + ( 100 + 1 ) x 100 : 2 = 5050

x + 101 x 100 : 2 = 5050

x + 5050 = 5050

x = 5050 - 5050

=> x = 0

 Vậy x = 0

Answer 7

Ta có:( x + 1 ) + ( x + 2 ) + ( x + 3 ) + ... + ( x + 100 ) = 5050

<=> (x + x + x + .....+ x) + ...... + (1 + 2 + 3 + ..... + 100) = 5050

<=> 100x + 5050 = 5050

=> 100x = 0

=> x = 0
