Answer 1

z=0,057

v=0,23

Прости если неверно

Answer 2

2z/3 - 5v/4= -3

z=36/5 - 21/20v

2(36/5 - 21/20 v) / 3 - 5v/4 = -3

72/5 - 21/10 v / 3 - 5v/4 = -3

144-21v/10/3 - 5v/4 = -3

144-21v / 30 - 5v/4 = -3

2(144-21v) - 75v = -180

288-42v-75v= -180

288 - 117v= -180

-117v= -468

v=4

z= 36/5 - 21/20 ×4

z=36/5-21/5

z= 3

Ответ : z=3, v=4
