Ответ:

x = 3,5

Пошаговое объяснение:

$\frac{17,7-2,6:1\frac{1}{3} }{4x}$ = $\frac{5-\frac{1}{5}*2,5 }{(\frac{23}{5}+\frac{7}{3}):1\frac{11}{15} }$

$\frac{\frac{177}{10}-\frac{13}{5}*\frac{3}{4}}{4x} = \frac{5-\frac{1}{2} }{\frac{104}{15}*\frac{15}{26} }$

$\frac{\frac{177}{10}-\frac{39}{20} }{4x} = \frac{\frac{9}{2} }{4}$

$\frac{\frac{63}{4} }{4x}=\frac{9}{8}$

$\frac{63}{16x}=\frac{9}{8}$

504 = 144x

144x = 504

$x=\frac{7}{2}$

$\frac{7}{2} = 3,5$
