Answer 1

Ответ:

2) $\frac{36}{7-\frac{5}{6}x }=8$

$36= 8*(7-\frac{5}{6}x)\\36=56-\frac{40}{6}x\\\frac{40}{6}x= 20\\ x=\frac{20*6}{40} =3$

3) $\frac{27}{5\frac{1}{3}+ \frac{1}{9}x } =4,5$

$27=4,5*(5\frac{1}{3}+ \frac{1}{9}x)\\27= \frac{45}{10} *(\frac{16}{3} +\frac{1}{9}x)\\27= 24+0.5x\\0.5x=3\\x=6$
