Развяжите пж 2 и 3 уравнение, пжпжпжпжпжпж!!!!!!!!!!!!!

Answer 1

2)

$1 \frac{1}{5} x = - 2 \frac{7}{10} \\ x = - 2 \frac{7}{10} \div 1 \frac{1}{5} \\ x = - \frac{27 \times 5}{10 \times 6} \\ x = - \frac{9 }{2 \times 2} \\ x = - \frac{9}{4} \\ x = - 2 \frac{1}{4}$

3)

$1 \frac{1}{63} \div x = - \frac{8}{21} \\ x = 1 \frac{1}{63} \div ( - \frac{8}{21} ) \\ x = - \frac{64 \times 21}{63 \times 8} \\ x= - \frac{8}{3} \\ x = - 2 \frac{2}{3}$
