Answer 1

Ответ:

$1)x - 2 \frac{7}{12} = 5 \frac{3}{18}$

$x = 5 \frac{3}{18} + 2 \frac{7}{12}$

$x = \frac{31}{6} + \frac{31}{12}$

$x = \frac{62 + 31}{12}$

$x = \frac{93}{12}$

$x = \frac{31}{4}$

$x =7 \frac{3}{4}$

$2)x - 26 \frac{7}{21} = 100 \frac{5}{28}$

$x = 100 \frac{5}{28} + 26 \frac{7}{21}$

$x = 126 \frac{15 + 28}{84}$

$x = 126 \frac{43}{84}$
