\(\left(x-\frac{1}{7}\right):\frac{2}{9}+\frac{1}{11}=\frac{100}{11}\)
\(\left(x-\frac{1}{7}\right):\frac{2}{9}=\frac{100}{11}-\frac{1}{11}\)
\(\left(x-\frac{1}{7}\right):\frac{2}{9}=9\)
\(\left(x-\frac{1}{7}\right)=9\cdot\frac{2}{9}\)
\(x-\frac{1}{7}=2\)
\(x=2+\frac{1}{7}\)
\(x=\frac{15}{7}\)
\(\left(x-\frac{1}{7}\right):\frac{2}{9}+\frac{1}{11}=\frac{100}{11}\)
\(\Rightarrow\left(x-\frac{1}{7}\right).\frac{9}{2}+\frac{1}{11}=\frac{100}{11}\)
\(\Rightarrow\left(x-\frac{1}{7}\right).\frac{9}{2}=\frac{100}{11}-\frac{1}{11}\)
\(\Rightarrow\left(x-\frac{1}{7}\right).\frac{9}{2}=\frac{99}{11}\)
\(\Rightarrow\left(x-\frac{1}{7}\right).\frac{9}{2}=9\)
\(\Rightarrow\left(x-\frac{1}{7}\right)=9:\frac{9}{2}\)
\(\Rightarrow\left(x-\frac{1}{7}\right)=9.\frac{2}{9}\)
\(\Rightarrow x-\frac{1}{7}=2\)
\(\Rightarrow x=2+\frac{1}{7}\)
\(\Rightarrow x=\frac{15}{7}\)
\(\left(x-\frac{1}{7}\right):\frac{2}{9}+\frac{1}{11}=\frac{100}{11}\)
\(\left(x-\frac{1}{7}\right):\frac{2}{9}=\frac{100}{11}-\frac{1}{11}\)
\(\left(x-\frac{1}{7}\right):\frac{2}{9}=9\)
\(x-\frac{1}{7}=9\times\frac{2}{9}\)
\(x-\frac{1}{7}=2\)
\(x=2+\frac{1}{7}\)
\(x=2\frac{1}{7}\)
( x - 1/7) : 2/9 + 1/11 = 100/11
(x - 1/7) : 2/9 = 100/11 - 1/11
(x - 1/7) : 2/9 = 9
x - 1/7 = 9 x 2/9
x - 1/7 = 2
x = 2 + 1/7
x = 15/7
Chúc bạn hok tốt nha!
\(\left(x-\frac{1}{7}\right)\div\frac{2}{9}+\frac{1}{11}=\frac{100}{11}\)
\(\Leftrightarrow\left(x-\frac{1}{7}\right)\div\frac{2}{9}=\frac{100}{11}-\frac{1}{11}\)
\(\Leftrightarrow\left(x-\frac{1}{7}\right)\div\frac{2}{9}=9\)
\(\Leftrightarrow x-\frac{1}{7}=9\times\frac{2}{9}\)
\(\Leftrightarrow x-\frac{1}{7}=2\)
\(\Leftrightarrow x=2+\frac{1}{7}\)
\(\Leftrightarrow x=\frac{15}{7}\)
Vậy x=\(\frac{15}{7}\)
_Chúc bạn học tốt_
