18. ( x - 16 ) = 18
x - 16 = 18 : 18
x - 16 = 1
x = 1 + 16
x = 17
Vậy x = 17
18 . ( x - 16 ) = 18
Vì số nào nhân vs 1 cũng bằng chính nó nên:
x - 16 = 1
=> x = 17
18.(x-16)=18
(x-16)=18:18
(x-16)=1
x=1+16
x=17
\(18.\left(x-6\right)=18\)
\(x-6=18:18\)
\(x-6=1\)
\(x=1+6\)
\(x=7\)
vậy \(x=7\)
\(18.\left(x-16\right)=18\)
\(\Rightarrow x-16=1\)
\(\Rightarrow x=17\)
Vậy x = 17
18. ( x - 16 ) = 18
x - 16 = 18 : 18 (TSBC)
x - 16 = 1
x = 16+1 = 17
18.(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-16) = 18
x - 16 = 18:18
x - 16 = 1
x = 1+16
x = 17
