18 x ( x - 16 )=18
( x - 16 )=18:18
( x - 16 )=1
x =16 +1
x =17
18x(x-16)=18
x-16 =18:18
x-16 =1
x =1+16
x =17
18.(x-16)=18
X-16=18-18
x-16=0
x=0+16
x=16
k cho mình. Bạn nha
Ta có : 18 . ( x - 16 ) = 18
x - 16 = 18:18
x - 16 = 1
x = 1 + 16
x = 17
Vậy x = 17
18 x ( x - 16 ) = 18
18 x X -16 = 18 ( Buoc nay pha ngoac )
18 x X = 18 - 16
18 x X = 2
X = 18 : 2
X = 9
18 x ( x - 16 ) = 18
x - 16 = 18 : 18
x - 16 = 1
x = 1 + 16
x = 17.
18 x ( x - 16 ) = 18
x - 16 = 18 : 18
x - 16 =1
x = 1 + 16
x = 17
Vậy x = 17
18 x ( x - 16 ) = 18
x - 16 = 18 : 18
x - 16 = 1
x = 1 + 16
x = 17
18x(x-16)=18
x-16=18:18
x-16=1
x=16+1
x=17
18*(x - 16) = 18
x -16 = 18:18
x - 16 = 1
x = 1+16
x = 17
18 x ( x - 16 ) = 18
( x - 16 ) = 18 : 18
( x - 16 ) = 1
x = 16 + 1
x = 17
Vậy x = 17
