Question

4-(27-3)=x-(13-4)

Answer 1

4 - ( 27 - 3) = x - ( 13 - 4 )

4 - 24        = x - 9

- 20           = x - 9

x - 9          = - 20

x               = -11

vậy: x = -11

Answer 2

4 - (27 - 3) = x - (13 - 4)

4 - 24 = x - 9

-20 = x - 9

x - 9 = -20

x = (-20) + 9

x = -11

Answer 3

4 - (27 - 3) = x - (13 - 4)

4 - 24 = x - 9

-20 = x - 9

x - 9 = -20

x = (-20) + 9

x = -11

Answer 4

4 - (27 - 3) = x - (13 - 4)

4 - 24 = x - 9

-20 = x - 9

x - 9 = -20

x = (-20) + 9

x = -11
