Question

X+( x+1)+(x+2)+.......+(x+100)=10100

Giúp mình nhé

Answer 1

x + ( x + 1 ) + ( x + 2 ) + ... + ( x + 100 ) = 10100

x + x + 1 + x + 2 + ... + x + 100 = 10100

( x + x + x + ... + x ) + ( 1 + 2 + ... + 100 ) = 10100

101x + 5050 = 10100

101x = 5050

x = 50

Vậy x = 50

Answer 2

X + (X + 1) + (X + 2) + .... + (X + 100) = 10100

X + (X + X + ... + X) + (1 + 2 + .... + 100) = 10100

X + X x 100 + 5050 = 10100

X x 101 = 10100 - 5050

X x 101 = 5050

X           = 5050 : 101

X           = 50
