Answer:

93

Step-by-step explanation:

x2002+10x200110x2000=957.9

Multiplying both the sides by 10

x2002+10x2001x2000=9579

∴x2002x2000+10x2001x2000=9579

∴x2002−2000+10x2001−2000=9579 ……… (aman=am−n)

∴x2+10x−9579=0

∴x2+10x+25−25−9579=0 .[Add 25 to make x2+10x a perfect square]

∴lx2+10x+25−9604=0

∴(x+5)2−(98)2=0

∴(x+5+98)

(x+5−98)=0

∴(x+103)(x−93)=0

∴x+103=0 or x−93=0

∴x=−103 or x=93
