Answer 1

$1)\frac{3m+5}{4}=\frac{5m+1}{3}\\\\\frac{3m+5}{4}*12=\frac{5m+1}{3}*12\\\\3(3m+5)=4(5m+1)\\\\9m+15=20m+4\\\\9m-20m=4-15\\\\-11m=-11\\\\m=1\\\\Otvet:\boxed{1}$

$2)\frac{5x+3}{5}=\frac{x-5}{8}\\\\\frac{5x+3}{5}*40=\frac{x-5}{8}*40\\\\8(5x+3)=5(x-5)\\\\40x+24=5x-25\\\\40x-5x=-25-24\\\\35x=-49\\\\x=-\frac{49}{35} =-\frac{7}{5}=-1,4\\\\Otvet:\boxed{-1,4}$
