Question

219-7(x+1)=100

Answer 1

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

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

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

\(x+1=119:7\)

\(x+1=17\)

\(x=17-1=16\)

Answer 2

 7(x+1)=219-100

7(x+1)=119

x+1=119:7

x+1=17

x=17-1

x=16

Answer 3

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

\(\Leftrightarrow7\left(x+1\right)=119\)

\(\Leftrightarrow x+1=17\)

\(\Leftrightarrow x=16\)

Vậy x = 16
