Question

х -(7 5/9 - 5 1/6)=-8 1/14
​

Answer 1

Ответ:

$x - (7 \frac{5}{9} - 5 \frac{1}{6} ) = - 8 \frac{1}{14} \\ x - 2 \frac{10 - 3}{18} = - 8 \frac{1}{14} \\ x - 2 \frac{7}{18} = - 8 \frac{1}{14} \\ x = - 8 \frac{1}{14} + 2 \frac{7}{18} \\ x = - 6 \frac{9 + 49}{126} = - 6\frac{ 58}{126} \\ x = - 6 \frac{29}{63}$
