Question

x + ( x + 1 ) + ( x + 2 ) + ( x + 3 ) + ......... + ( x + 100 ) = 5353

Answer 1

\(x+\left(x+1\right)+\left(x+2\right)+\left(x+3\right)+....+\left(x+100\right)=5353\)

\(x+\left(x+x+x+...+x\right)+\left(1+2+3+...+100\right)=5353\)

\(101x+\frac{\left(1+100\right)\times100}{2}=5353\)

\(101x+5050=5353\)

\(101x=5353-5050\)

\(101x=303\)

\(\Rightarrow x=3\)

Answer 2

x + ( x + 1 ) + ( x + 2 ) + ( x + 3 ) + ......... + ( x + 100 ) = 535

101 x + ( 1 + 2 + ... + 100 ) = 535 

101x + 5050 = 535

101x = -4515

\(\Rightarrow x=-\frac{4545}{101}\)

Answer 3

x + ( x + 1 ) + ( x + 2 ) + ( x + 3 ) + ......... + ( x + 100 ) = 5353

(x+x+x+x+...+x)+(1+2+3+...+100)=5353

      101x           +       5050         =5353

                      101x                    =5353 - 5050

                       101x                    =303

                        x                        =303 : 101

                        x                        = 3

Vậy ...

Answer 4

x + ( x + 1 ) + ( x + 2 ) + ( x + 3 ) + ......... + ( x + 100 ) = 5353

x + (x+x+x+x+x+…+x)+(1+2+3+…+100) = 5353

           101x                 +         5050            =5353

                                  101x                         =5353 – 5050

                                  101x                         =303

                                    x                             =303 : 101

                                   x                              =3

Answer 5

x+(x+1)+(x+2)+(x+3)+.....+(x+100)=5353

(x+x+x+x+.....+x)+(1+2+3+....+100)=5353   (có 101 số x)

101x + (1+100)x100:2=5353

101x+5050=5353

101x=303

x=303:101

x=3
