Пошаговое объяснение:

-x + 19ц.1/3 = 10ц.3/7

x = 19ц.1/3 - 10ц.3/7

x = 19ц.7/21 - 10ц.9/21

x = 8ц.19/21

=================

-x + (-22ц.1/4) = 30,2

-x - 22ц.1/4 = 30,2

x = -22,25 - 30,2

x = -52,45

=======================

-x + 27ц.1/3 = -20ц.5/9

x = 27ц.1/3 + 20ц.5/9

x = 27ц.3/9 + 20ц.5/9

x = 47ц.8/9

======================

-x + (-5,5) = -17ц.1/7

-x - 5,5 = -17ц.1/7

x = 17ц.1/7 - 5,5

x = 17ц.1/7 - 5ц.1/2

x = 17ц.2/14 - 5ц.7/14

x = 11ц.9/14
