Question

Tìm x

219 - 7 ( x + 1 ) = 100 
Giải hộ mình với, thanks

Answer 1

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 2

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

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

\(\Rightarrow x+1=17\)

\(\Rightarrow x=16\)

Vậy \(x=16\)
