Chúng bn hok giỏi nha quynh261120
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
\(96-3.\left(x+1\right)=42\)
\(3.\left(x+1\right)=96-42\)
\(3.\left(x+1\right)=54\)
\(x+1=54:3\)
\(x+1=18\)
\(x=18-1\)
\(x=17\)
k mk nha
Ta có :
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
