помогите пожалуйста с алгеброй​

Answer 1

$1)\frac{17p-1}{4} *12+\frac{3-p}{6}*12<p*12\\\\3(17p-1)+2(3-p)<12p\\\\51p-3+6-2p<12p\\\\49p-12p<-3\\\\39p<-3\\\\p<-\frac{3}{39}\\\\p<-\frac{1}{13}$

$2)m*8-\frac{2m+1}{2}*8<\frac{m-5}{8}*8\\\\8m-4(2m+1)<m-5\\\\8m-8m-4<m-5\\\\-4<m-5\\\\-m<-5+4\\\\-m<-1\\\\m>1$

$3)\frac{y-1}{5}*15-y*15<\frac{y}{15} *15\\\\3(y-1)-15y<y\\\\3y-3-15y<y\\\\-12y-y<3\\\\-13y<3\\\\y>-\frac{3}{13}\\\\Otvet:\boxed{0}$

$4)\frac{2y-4}{3}*15-\frac{y+1}{5}*15>1*15\\\\5(2y-4)-3(y+1)>15\\\\10y-20-3y-3>15\\\\7y>15+23\\\\7y>38\\\\y>5\frac{3}{7} \\\\Otvet:\boxed{6}$
