Question

4целые 5/14-(x-7целых 3/14)=2целых 9/14

Answer 1

$4\frac{5}{14}-(x-7\frac{3}{14})=2\frac{9}{14}\\\frac{61}{14}-(x-\frac{101}{14})=\frac{37}{14}\\\frac{61}{14}-x+\frac{101}{14}=\frac{37}{14}\\\frac{81}{7}-x=\frac{37}{14}\\-x=\frac{37}{14}-\frac{81}{7}\\-x=-\frac{125}{14}\\x=\frac{125}{14}$

Answer 2

Ответ:

Пошаговое объяснение:

4. 5/14 - (х - 7. 3/14) = 2. 9/14

х - 7. 3/14 = 4. 5/14 - 2. 9/14

х - 7. 3/14 = 3. 19/14 - 2. 9/14

х - 7. 3/14 = 1. 10/14

х = 1. 10/14 + 7. 3/14

х = 8. 13/14
