Bài 1: tìm x 

4+x:6=7 

Bài 2:tìm x

96-(x+1) = 42 

giúp tui nha :<

Answer 1

B1:

4 + x : 6 = 7

<=> x : 6 = 3

<=> x = 18

B2:

96 - (x + 1) = 42

<=> x + 1 = 50

<=> x = 49

Answer 2

\(4+x:6=7\)

\(x:6=7-4\)

`x:6=3`

`x=3*6`

`=>x=18`

\(96-\left(x+1\right)=42\)

`x+1=96-42`

`x+1=54`

`x=54-1`

`=>x=53`

Answer 3

`1)`

4 + x : 6= 7`

`=> x : 6 = 7 - 4`

`=> x : 6 = 3`

`=> x      = 3 xx 6`

`=> x      = 18`

`2)`

`96 - (x+1) = 42`

`=>    x + 1 = 96 - 42`

`=>    x + 1 = 54`

`=>     x       = 54 - 1`

`=>     x      = 53`

Answer 4

\(x:6=3\\ x=3.6\\ x=18\\ 2,\\ x+1=96-42\\ x+1=54\\ x=54-1\\ x=53\)

Answer 5

1

4 + x : 6 = 7

     x : 6 = 7- 4

     x : 6 = 3

     x = 3 x 6

     x = 18

2.

96-(x+1)=42

      x +1 = 96 - 42

      x + 1 = 54

      x      = 54-1

      x      = 53
