$\left(\frac{9}{4}+\frac{1}{3}×\frac{3}{5}×\frac{1}{5}-\frac{9}{5}\right) : x = x : \left(\frac{7}{8}×\frac{1}{14}+\frac{3}{2}\right)$

$\left(\frac{9}{4}+\frac{\cancel3^1}{\cancel{75}_{25}}-\frac{9}{5}\right) : x = x : \left(\frac{\cancel7^1}{8}×\frac{1}{\cancel{14}_2}+\frac{3}{2}\right)$

$\left(\frac{9}{4}+\frac{1}{25}-\frac{9}{5}\right) : x = x : \left(\frac{1}{16}+\frac{3}{2}\right)$

$\left(\frac{225+4-180}{100}\right) : x = x : \left(\frac{1+24}{16}\right)$

$\left(\frac{49}{100}\right) : x = x : \left(\frac{25}{16}\right)$

$x×x = \frac{49}{\cancel{100}_4}×\frac{\cancel{25}^1}{16}$

$x^2 = \frac{49}{4}×\frac{1}{16}$

$x^2 = \frac{49}{64}$

$\sqrt{x^2} = \sqrt{\frac{49}{64}}$

$x= \pm\frac{7}{8}$
