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
\(96-3.\left(x+1\right)=42.\)
\(3.\left(x+1\right)=96-42\)
\(3.\left(x+1\right)=54\)
\(x+1=54:3\)
\(x+1=18\)
\(\Rightarrow x=17\)
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) = 54
=> x + 1 = 18
=> x = 17
vậy_
\(96-3(x+1)=42\)
\(\Rightarrow3(x+1)=96-42\)
\(\Rightarrow3(x+1)=54\)
\(\Rightarrow x+1=54\div3\)
\(\Rightarrow x+1=18\)
\(\Rightarrow x=18-1\)
\(\Rightarrow x=17\)
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
96 -3x - 3 = 42
-3x = 42 - 96 +3
-3x =- 51
x =-51 / -3
x = 17
hc tôt nha bn
96-39(x+1)=42
