Ta có :18 . (x - 16) = 18
<=> x - 16 = 18 : 18
<=> x - 16 = 1
<=> x = 1 + 16
<=> x = 17
Vậy S={17}
18 . (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 = 1
x = 1 + 16
x = 17
Ai tk mik mik tk lại
\(18.\left(x-16\right)=18\)
\(x-16=1\)
\(x=17\)
vay \(x=17\)
18.(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 = 1
x = 1 + 16
x = 17
Vậy x = 17
X - 16 = 18 : 18
X - 16 = 1
X = 1 + 16 =17
18.(x-16)=18
x-16 = 18:18
x-16 =1
x = 1+16
x 17
