Question

219-7<x+1>=100

Answer 1

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

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

\(\Leftrightarrow\)\(7\times\left(x+1\right)=119\)

\(\Leftrightarrow\)\(x+1=119\div7\)

\(\Leftrightarrow\)\(x+1=17\)

\(\Leftrightarrow\)\(x=17-1\)

\(\Leftrightarrow\)\(x=16\)

\(Vậy\)\(x\)\(=\)\(16\)
