Question

814-(x-305)=712.x=

 

Answer 1

814 - (x - 305) = 712x

814 - x + 305 = 712x

x + 509 = 712x

509 = 711x

x = 509/711 

Answer 2

 814 - ( x -305) = 712 

x - 305 = 814 - 712

x - 305 = 102

x = 102 + 305

x = 407

Vậy x = 407 :)

Answer 3

814 - (x - 305) = 712x

814 - x + 305 = 712x

x + 509 = 712x

509 = 711x

x = 509/711 

đúng 100%

Answer 4

814 - (x - 305) = 712x

814 - x + 305 = 712x

x + 509 = 712x

509 = 711x

x = 509/711 

Answer 5

814-(x-305)=712x

814-x+305=712x

1119=713x

x=1119/713
