Answer 1

Ответ:

x=1.5

Пошаговое объяснение:

$\displaystyle\\\bigg(1\frac{5}{6} x+\frac{7}{8}\bigg)}:1\frac{7}{8} =4\frac{1}{5} -2\frac{4}{15}\\\\\\\bigg(\frac{11}{6} x+\frac{7}{8}\bigg)}:\frac{15}{8} =\frac{21}{5} -\frac{34}{15}\\\\\\\bigg(\frac{11}{6} x+\frac{7}{8}\bigg)}:\frac{15}{8} =\frac{63-34}{15}\\\\\\ \frac{11}{6} x\cdot\frac{8}{15} +\frac{7}{8}\cdot\frac{8}{15}=\frac{29}{15}\\\\\\\frac{11*4}{3*15}x+\frac{7}{15}=\frac{29}{15}\\\\\\\frac{44}{45}x=\frac{29-7}{15}\\\\\\\frac{44}{45}x=\frac{22}{15}\\\\\\x=\frac{22}{15}:\frac{44}{45}$

$\displaystyle\\x=\frac{22}{15} \cdot\frac{45}{44} \\\\\\x=\frac{3}{2} \\\\\\x=1.5$
