\(A=\left(9\frac{3}{4}:5,2+x.2\frac{7}{24}\right):1\frac{9}{16}=6\)
\(A=\left(9\frac{3}{4}:5,2+x.2\frac{7}{24}\right)=\frac{75}{8}\)
\(A=\left(2\frac{7}{24}.\frac{9}{11}+x.2\frac{7}{24}\right)=\frac{75}{8}\)
\(A=\left[2\frac{7}{24}.\left(\frac{9}{11}+x\right)\right]=\frac{75}{8}\)
\(A=\frac{9}{11}+x=\frac{45}{11}\)
\(x=\frac{45}{11}-\frac{9}{11}\)
\(x=\frac{36}{11}\)
