Question

5x+x=36

2(x+4)-32=18

7x-2x=50

 

Answer 1

5x + x = 36

6x       = 36

 x        = 36 : 6

 x         = 6

Vậy x = 6

2 ( x + 4 ) - 32 = 18

2 ( x + 4 )        = 18 + 32

2 ( x + 4 )        = 50

     x + 4          = 50 : 2

     x + 4          = 25

     x                = 25 - 4 

     x                = 21

Vậy x = 21

7x - 2x = 50

5x        = 50 

 x         = 50 : 5

 x         = 10

Vậy x = 10

Chúc hok tốt

Answer 2

=>6x=36

       X=36:6

       X=6

Vậy.......

Answer 3

5x + x = 36

6x = 36

x = 6

2 ( x + 4 ) - 32 = 18

2 ( x + 4 ) = 50

x + 4 = 25

x = 21

7x - 2x = 50

5x = 50

x = 10

Answer 4

5x + x = 36

      6x = 36

        x = 36 : 6

        x = 6

2(x + 4) - 32 = 18

      2(x + 4 ) = 18 + 32

      2(x + 4) = 50

         x + 4 = 50 : 2

         x + 4 = 25

              x = 25 - 4 = 21

7x - 2x = 50

      5x = 50

        x = 50 : 5 = 10

Answer 5

2(x+4)-32=18

  2(x+4)=32+18

   2(x+4)=50

     X+4 =50:2

     X+4=25

     X=25-4

      X=21

Answer 6

=>5x=50

     X =50:5

     X=10

Vậy.......

Answer 7

BÀI 1:

\(5x+x=36\)

\(6x=36\)

\(x=6\)

BÀI 2:

\(2\cdot\left(x+4\right)-32=18\)

:\(2\cdot x+2\cdot4=50\)

\(2\cdot x+8=50\)

\(2\cdot x=42\)

\(x=21\)

BÀI 3:

\(7x-2x=50\)

\(5x=50\)

\(x=10\)

\(goodluck!!!!hi\)

Answer 8

5x+x =36

5x+1x=36

6x=36

x=6

2(x+4)-32=18

2(x+4) =18+32

X+4=50:2

x=25-4

tự bít

7x-2x=50

5x=50

x=50:5

x=10

Answer 9

\(5x+x=36\)

\(5x+x.1=36\)

\(x.\left(5+1\right)=36\)

\(x.6=36\)

\(\Rightarrow x=6\)

____________

\(2.\left(x+4\right)-32=18\)

\(2.\left(x+4\right)=18+32\)

\(2.\left(x+4\right)=50\)

      \(x+4=50:2\)

      \(x+4=25\)

      \(\Rightarrow x=21\)

___________________

\(7x-2x=50\)

\(x.\left(7-2\right)=50\)

\(x.5=50\)

\(\Rightarrow x=10\)
