Question

Tìm x

96 - 3 . ( x + 1 ) = 42

Answer 1

96 - 3(x + 1) = 42

<=> 96 - 3x - 3 = 42

<=> 96 - 3 - 42 = 3x

<=> 3x = 51

<=> x = 17

Answer 2

\(96-3\left(x+1\right)=42\)

\(3\left(x+1\right)=96-42=54\)

\(x+1=54:3=18\)

\(x=18-1=17\)

Answer 3

Answer 4

\(96-3\left(x+1\right)=42\)

\(\Leftrightarrow x+1=18\)

hay x=17

Answer 5

3.(x+1)=96-42

3.(x+1)=54

x+1=54:3

x+1=18

x=18-1

x=17

Answer 6

\(96-3.\left(x+1\right)=42\)

\(\Rightarrow3.\left(x+1\right)=54\)

\(\Rightarrow x+1=18\)

\(\Rightarrow x=17\)

Answer 7

96 - 3 . ( x + 1 ) = 42

       3.(x+1)=96-42

       3.(x+1)=54

           x+1=54:3

           x+1=18

           x=18-1

           x=17

vậy x=17

 

Answer 8

`96-3 . (x+1)=42`

`<=> 3.(x+1)=96-42`

`<=>3.(x+1)=54`

`<=>x+1=54:3`

`<=>x+1=18`

`<=> x = 18-1`

`<=>x=17`
