Answer 2

\(319-7.\left(x+1\right)=200\)

\(\Rightarrow7.\left(x+1\right)=319-200\)

\(\Rightarrow7.\left(x+1\right)=119\)

\(\Rightarrow x+1=119:7=17\)

\(\Rightarrow x=17-1=16\)

Vậy : \(x=16\)

Answer 3

7 . ( x + 1 ) = 319 -200

7 . (x + 1 ) =119

( x + 1) =119 : 7

x + 1 = 17

x =17 -1

x =16

Vậy x = 16
