Решите уравнение:
1)
$x + 1\frac{4}{9} = 4\frac{2}{7}$
$x = 4\frac{2}{7}^{/9} - 1\frac{4}{9}^{/7}$
$x = 4\frac{}{63} - 1\frac{}{63}$
$x = 3\frac{}{63} - 1\frac{}{63}$
x =
2)
$6\frac{11}{12} - x = 3\frac{7}{9}$
$x = 6\frac{11}{12}^{/} - 3\frac{7}{9}^{/}$
3)
$x - 1\frac{3}{10} = 2\frac{6}{35}$
$x + 1\frac{4}{9} = 4\frac{2}{7}$
$x = 4\frac{2}{7}^{/9} - 1\frac{4}{9}^{/7}$
$x = 4\frac{18}{63} - 1\frac{28}{63}$
$x = 3\frac{81}{63} - 1\frac{28}{63}$
$x = 2\frac{53}{63}$
Ответ: $x = 2\frac{53}{63}$
$6\frac{11}{12} - x = 3\frac{7}{9}$
$x = 6\frac{11}{12}^{/3} - 3\frac{7}{9}^{/4}$
$x = 6\frac{33}{36} - 3\frac{28}{36}$
$x = 3\frac{5}{36}$
Ответ: $x = 3\frac{5}{36}$
$x - 1\frac{3}{10} = 2\frac{6}{35}$
$x = 2\frac{6}{35}^{/2} + 1\frac{3}{10}^{/7}$
$x = 2\frac{12}{70} + 1\frac{21}{70}$
$x = 3\frac{33}{70}$
Ответ: $x = 3\frac{33}{70}$
