Answer 1

$\frac{3x-1}{5} - \frac{2x+6}{8} = 5\\ 8(3x-1)-5(2x+6)=200\\24x - 8 - 10x - 30 = 200\\14x-38=200\\14x=200+38\\14x=238\\x=17$          $\frac{3a-2}{4} + \frac{2-a}{6} =1\\ 3(3a-2)+2(2-a)=12\\9a-6+4-2a=12\\7a-2=12\\71=12+2\\7a=14\\a=2$

$\frac{5a}{6}-\frac{2a+1}{2} =0\\ 5a-3(2a+1)=0\\5a-6a-3=0\\-a-3=0\\-a=3\\a=-3$
