(Полное условие - в демо-файлах)
Выберите один ответ:
z′x = – (xy+(y+3z²+x²y²z²)) / yz ; z′y = – (xy+(y+3z²+x²y²z²)) / (xz+z(1+x²y²z²))
z′x = – (xy+y+3z²(1+x²y²z²)) / yz ; z′y = – (xy+y+3z²(1+x²y²z²)) / (xz+z(1+x²y²z²))
z′x = – (xy+y+3z²+x²y²z²) / yz ; z′y = – (xy+y+3z²+x²y²z²) / (xz+z(1+x²y²z²))
z′x = – (xy+(y+3z²)(1+x²y²z²)) / yz ; z′y = – (xy+(y+3z²)(1+x²y²z²)) / (xz+z(1+x²y²z²))
