Question

Tìm x. 

18 - ( x + 2 ) = 12

Help me. 

Answer 1

\(18-\left(x+2\right)=12\)

\(=>x+2=18-12=6\)

\(=>x=6-2=4\)

Answer 2

18 - ( x + 2 ) = 12

<=>18-x-2=12

<=>16-x=12

<=>x=16-12

<=>x=4

Vậy x=4

Answer 3

\(18-\left(x+2\right)=12\)

\(\Leftrightarrow x+2=18-12\)

\(\Leftrightarrow x+2=6\)

\(\Leftrightarrow x=6-2\)

\(\Leftrightarrow x=4\)

Vậy \(x=4\)

Answer 4

Trl :

18 - ( x + 2 ) = 12

         x + 2    = 18 - 12

         x + 2    =    6

         x          = 6 - 2 

         x          =  4

Answer 5

18-(x+2)=12

       x+2=18-12

       x+2=6

       x    =6-2

       x    =4

Answer 6

18 - ( x + 2 ) = 12

x + 2 = 18 - 12

x + 2 = 6

      x = 6 - 2

      x = 4

Vậy x = 4

Answer 7

( x + 2 ) = 18 - 12

  x + 2   =       6

  x         =  6 - 2

  x         =     4

Answer 8

18-(x+2)=12

       x+2=18-12

       x+2=6

       x    =6-2

       x    =4
