1 задание. (17х+у)/6х+(3х-8у)/6х=(17х+у+3х-8у)/6х=(20х-7у)/6х. Ответ:№3
2 задание (11х-5у)/8х-(5х+7у)/8х=(11х-5у-5х-7у)/8х=(6х-12у)/8х. Ответ:№1
3 задание (а²+2ab)/a-4b-(10ab-16b²)/a-4b=(a²+2ab-10ab+16b²)/a-4b= (a²-8ab+16b²)/a-4b=(a-4b)²/a-4b=a-4b
4 задание (4х+у)/10+(6х-5у)/4-х=(4(4х+у)+10(6х-5у)-40х)/40=(16х+4у+60х-50у-40х)/40=(36х-46у)/40
