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 . ( 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
3. (x + 1 ) = 54
x + 1 = 54 : 3
x + 1 = 18
x = 18 - 1
x = 17
k mk nha bạn, thank bạn nhìu
96 - 3.(x + 1) = 42
3.(x + 1) = 96 - 42

x = 18 - 1
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
