Answer 1

900x900+9000=x+700

=> 819000      =x + 700

=> x + 700     = 819000

=> x              = 819000 - 700

=> x              = 818300

Answer 2

900.900+9000=x+700

810000+9000=x+700

819000=x+700

x=819000-700

x=818300

Answer 3

900x900+900=x+700

810000+900=x+700

810900           =x+700

x                      =810200

Answer 4

180000+9000=x+700

189000=x+700

x=189000-700=818300

Answer 5

Trả lời :

900 x 900 + 9000 = x + 700

=> x + 700 = 900 x 900 + 9000

=> x = 819000 - 700

x = 818300

Vậy x = 818300
