Question

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

Answer 1

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

4 - 24 = x - 9

- 20 = x - 9

x = - 20 + 9

x = - 11

Answer 2

\(4-\left(27-3\right)=x-\left(13-4\right)\)

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

\(-20=x-13+4\)

\(-20-4=x-13\)

\(-24=x-13\)

\(-24+13=x\)

\(-11=x\)

Answer 3

\(4-\left(27-3\right)=x-\left(13-4\right)\)

\(4-\left(27+3\right)=x-9\)

\(-20=x-9\)

\(x=-20+9\)

\(x=-11\)

Answer 4

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

=> 4 - 24     = x - 9

=> 4 - 24 + 9 = x

=> -11           = x

=> x              = -11

Vậy :...

Chúc bn học giỏi^^

Answer 5

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

4-(27-3)=x-9

4-24      =x-9

-20        =x-9

=>x-9   = -20

    x       =(-20)+9

    x       = -11
