Question

219 - 7. ( x + 1 ) = 100

Answer 1

219 - 7 . (x + 1) = 100

\(\Rightarrow\) 7 . (x + 1) = 219 - 100

\(\Rightarrow\) 7 . (x + 1) = 119

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

\(\Rightarrow\) x + 1 = 17 \(\Rightarrow\) x = 17 - 1 \(\Rightarrow\) x = 16 Vậy: x = 16

Answer 2

\(219-7.\left(x+1\right)=100\)

\(7.\left(x+1\right)=219-100\)

\(7.\left(x+1\right)=119\)

\(\left(x+1\right)=119:7\)

\(\left(x+1\right)=17\)

\(x=17-1\)

\(x=16\)

Vậy \(x=16\)

Answer 3

219 - 7 . ( x + 1) = 100

7 . ( x + 1 ) = 219 - 100

7 . ( x + 1 ) = 119

x + 1 = 119 : 7

x + 1 = 17

x = 17 - 1

x = 16

Answer 4

16
