Question

x        +             3465            +456       =            9999

Answer 1

x + 3465 + 456 = 9999

x + 3465 = 9999 - 456

x + 3465 = 9543

x = 9543 - 3465

x = 6078 

Vậy x = 6078

Answer 2

x= 9999-456-3465=6078

Answer 3

x+ 3465+456= 9999

x+ 3912 = 9999

x= 9999 - 3912

x=6087

Answer 4

x=9999-456-3465

x=6087 

vậy x=6087

Answer 5

x + ( 3456 + 456 ) = 9999

x + 3912 = 9999

x = 9999 - 3912

x = 6087
