Answer 1

$1)\frac{2x-3}{8}+\frac{1-5x}{6}=3\\\\\frac{2x-3}{8}*24+\frac{1-5x}{6}*24=3*24\\\\3(2x-3)+4(1-5x)=72\\\\6x-9+4-20x=72\\\\-14x=72+5\\\\-14x=77\\\\\boxed{x=-5,5}\\\\\\2)x-\frac{5x+2}{8} =\frac{6x+7}{4}\\\\x*8-\frac{5x+2}{8}*8 =\frac{6x+7}{4}*8\\\\8x-(5x+2)=2(6x+7)\\\\8x-5x-2=12x+14\\\\3x-12x=14+2\\\\-9x=16\\\\\boxed{x=-1\frac{7}{9}}$
