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

c)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

Hzh

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

17

giúp tớ nhé tớ bị trừ 1090 điểm cảm ơn trước

96-3(x+1)=42

3(x+1)=96-42

3(x+1)=54

x+1=54-1

x+1=53

x=52

nha bn

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

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

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

\(96-3-3x=42\)

\(93-3x=42\)

\(3x=51\Rightarrow x=17\)

tik mik nha !!!

96 - 3 ( x+1 ) = 42

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

=> 3( x + 1) = 54

=> x+1 = 54 : 3

=> x + 1 = 18

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

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

x + 1 = 54 : 3 = 18

x = 18 - 1

x = 17

ko bít

96-3(x+1)=42

96 - 3 x ( x + 1 ) = 42 

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

x + 1 = 54 : 3 = 18

=> x = 18 - 1 

x = 17 

hok tốt

50 nha

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

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

            \(3.\left(x+1\right)=54\)

                  \(x+1=54:3\)

                  \(x+1=18\)

                  \(\Rightarrow x=17\)

Giải:

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

\(\Leftrightarrow3\left(x+1\right)=96-42\)

\(\Leftrightarrow3\left(x+1\right)=54\)

\(\Leftrightarrow x+1=\dfrac{54}{3}\)

\(\Leftrightarrow x+1=18\)

\(\Leftrightarrow x=18-1\)

\(\Leftrightarrow x=17\)

Vậy \(x=17\).

Chúc bạn học tốt!

96 - 3( x + 1 ) =42

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

x + 1 = 54 : 3

x + 1 = 18

x = 18 - 1 = 17

Vậy...

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
