Можно начать со отнимания 6х=25у+1 - 5х-16у=-4 получается х=9у+5 затем можно подставить значение y любое уравнение например 5(9у+5)-16у=-4 далее раскрываем скобки 45у+25-16у=-4 получается 29у=-29 получается у=-1 затем подставляем в любое уравнение вместо y -1 -5х+16=-4 далее -5х=-20 х= 4 минусы сократились

My husband and i met at a birthday party of my friend. we made friends and began to communicate. but i knew that he liked me. he beautifully took care about me and i fell in love. we spent all our free time together. of course, sometimes we had a quarrel. we broke up but then we realized that it was a really love and we decided to get married. then a boy was born in our family. many years have passed and we already have our grandchildren. and now we are celebrating our wedding anniversary.
