96 - 3(x+1)= 42

3(x+1) = 96 - 42 = 54

x + 1 = 54 : 3 = 18

x = 18 - 1 = 17

x=18-1=17

96-3.(x+1)=4²

96-3.(x+1)=16

93   .(x+1)=16

        (x+1)= 93-16

        (x+1)=77

         x      = 77-1

         x     =  76

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

96 - 3(x + 1) = 42

\(\Rightarrow\)3x + 3 = 54

\(\Rightarrow\)3x = 51

\(\Rightarrow\)x = 17

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

=> 3(x+1)=96-42

=> x+1=54:3

=> x=18-1

=> x=17

X=17 k đi

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

\(\Rightarrow3\left(x+1\right)=49\)

\(\Rightarrow x+1=\frac{49}{3}\)

\(\Rightarrow x=\frac{46}{3}\)

 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

3(x+1)=96-42

3(x+1)=54

x+1=54:3

x+1=18

x=17

đúng rồi

giup minh 96 - 3 × ( x + 1) = 42

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

3 ( x + 1 ) = 54

x + 1 = 54 : 3

x+1= 18

x = 18 - 1

x = 17

96-3(x+1)=42

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

x+1=54:3

x=17-1

x=16

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

3 ( x + 1 ) = 54

x + 1 = 54 : 3

x + 1 = 18

x = 18 - 1

x = 17
