Answer 1

(- 12) .(- 12) . x = 56 + 10 . 13 . x

=> 144 . x = 56 + 130 . x

=> 144 . x - 130 . x = 56

=> x . (144 - 130) = 56

=> x . 14 = 56

=> x = 56 : 14

=> x = 4

Vậy x = 4.

Answer 2

\(\left(-12\right)\left(-12\right).x=56+10.13.x\)

\(144.x=56+130.x\)

\(144.x-130.x=56\)

\(x.\left(144-130\right)=56\)

\(x.14=56\)

\(x=56:14\)

\(x=4\)

Answer 3

( -12 ) . ( - 12 ) . x = 56 + 10 . 13 . x 

144.x = 56 + 130.x 

144x = 130x + 56 

=> 144x - 130x = 56 

    14x = 65 

x = 56 : 14 = 4 

Vậy x = 4

Answer 4

Trả lời

(-12) (-12).x=56+10.13.x

     144     .x=56+130.x

144.x-130.x=56

x.(144-130)=56

x.14           =54

          =>x  =54:14

          =>x  =4.

Answer 5

( -12 ) . ( -12 ) x = 56 + 10 . 13 . x

144 . x = 56 + 130 . x

144 . x = 130 . x + 56

144 . x - 130 . x = 56

x . ( 144 - 130 ) = 56

14x = 56

    x = 56 : 14 

    x = 4

Vậy x = 4

Answer 6

(-12) . (-12) . x = 56 + 10 . 13.x

=> 144.x = 56 + 130x

=> 144x = 13x + 56

=> 144x - 130x = 56

=> 14x = 56

=> x=4
