67-(34+ y)+56=73
98-((45+z)-38)=42​

Answer 1

Пошаговое объяснение:

67-(34+у)+56=73

67-34-у+56=73

89-у=73

-у=73-89

-у= -16

у=16

98-((45+z)-38)=42

98-(45+z-38)=42

98-(7+z)=42

98-7-z=42

91-z=42

-z=42-91

-z= -49

z=49

Answer 2

Ответ:

67-34+у+56=73

89-у=73

-у=73-89

-у=-16

у=16

98-(45+z-38)=42

98-(7+z)=42

91-z=42

-z=42-91

-z=-4z=49
