\(2-\left(5\frac{3}{8}+x-7\frac{5}{24}\right):16\frac{2}{3}=0\)
\(2-\left(5\frac{3}{8}+x-7\frac{5}{24}\right):16\frac{2}{3}=0\)
\(2-\left(\frac{43}{8}+x-\frac{173}{24}\right)=0\)
\(\left(\frac{43}{8}+x-\frac{173}{24}\right)=-2\)
\(\frac{43}{8}+x=\frac{125}{24}\)
\(x=-\frac{1}{6}\)

\(1-\left(5\frac{3}{8}+x-7\frac{5}{24}\right):16\frac{2}{3}=0\)
\(\Rightarrow1-\left(\frac{43}{8}+x-\frac{173}{24}\right):\frac{50}{3}=0\)
\(\Rightarrow\left(\frac{43}{8}+x-\frac{173}{24}\right):\frac{50}{3}=1\)
\(\Rightarrow\frac{43}{8}+x-\frac{173}{24}=\frac{53}{3}\)
\(\Rightarrow\frac{43}{8}+x=\frac{53}{3}+\frac{173}{24}\)
\(\Rightarrow\frac{43}{8}+x=\frac{199}{8}\)
\(\Rightarrow x=\frac{199}{8}-\frac{43}{8}\)
\(\Rightarrow x=\frac{156}{8}=\frac{39}{2}\)

\(\left(-2+\left(\frac{3}{8}-\frac{5}{24}\right)+\frac{37}{9}x\right):\frac{50}{3}=1\)
\(\left(-2\frac{4}{24}+\frac{37}{9}x\right)=\frac{3}{50}\)
\(\frac{37}{9}x=\frac{3}{50}--2\frac{4}{24}=\frac{3}{50}+2\frac{4}{24}=2\frac{26}{100}=2\frac{13}{50}=\frac{113}{50}\)
\(x=\frac{113}{50}:\frac{37}{9}=\frac{113}{50}x\frac{9}{37}=\frac{1017}{1850}\)
vậy x=1017/1850
nếu chưa rút gọn về pstg thì các bn làm tiếp nhé đâu tay lắm

\(2-\left(5\frac{3}{8}+x-7\frac{5}{24}\right):16\frac{2}{3}=0\)\(\Rightarrow2-\left(\frac{43}{8}+x-\frac{173}{24}\right):\frac{50}{3}=0\)
\(\Rightarrow\left(\frac{43}{8}+x-\frac{173}{24}\right):\frac{50}{3}=2\Rightarrow\frac{43}{8}+x-\frac{173}{24}=2\times\frac{50}{3}\)
\(\Rightarrow\frac{43}{8}+x-\frac{173}{24}=\frac{100}{3}\Rightarrow x=\frac{100}{3}+\frac{173}{24}-\frac{43}{8}\Rightarrow x=\frac{211}{6}=35\frac{1}{6}\)
