Question

УМОЛЯЮ ПОЖАЛУЙСТА!!!​

Answer 1

Ответ:

1) 5 20/23 2) 5 1/16

Пошаговое объяснение:

1) 4 5/23 + x = 10 2/23

97/23 + x = 10 2/23

97/23 + x = 232/23

x = 232/23 - 97/23

x = 135/23

x = 5 20/23

2) 7 9/16 - (x - 2 3/16) = 4 11/16

121/16 - (x - 2 3/16) = 4 11/16

121/16 - (x - 35/16) = 4 11/16

121/16 - (x - 35/16) = 75/16

121/16 - x + 35/16 = 75/16

39/4 - x = 75/16

-x = 75/16 - 39/4

-x = - 81/16

x = 81/16

x = 5 1/16

Answer 2

$1) \\ 4 \frac{5}{23} + x = 10 \frac{2}{23} \\ x = 10 \frac{2}{23} - 4 \frac{5}{23} \\ x = 9 \frac{25}{23} - 4 \frac{5}{23} \\ x = 5 \frac{20}{23}$

$2)7 \frac{9}{16} - (x - 2 \frac{3}{16} ) = 4 \frac{11}{16} \\ - x = 3 \frac{27}{16} - 7 \frac{9}{16} - 2 \frac{3}{16} \\ - x = - 6 \frac{15}{16} \\ x = 6 \frac{15}{16}$
