Answer 1

$3 frac{1}{8} -x=2 frac{1}{8}$
$frac{25}{8} -x= frac{17}{8}$
$x= frac{25}{8} - frac{17}{8}$
$x= frac{8}{8} =1$

$12 frac{1}{15} -y=1 frac{1}{5}$
$frac{181}{15} -y= frac{6}{5}$
$y= frac{181}{15} - frac{6}{5}$
$y= frac{181-18}{15}$
$y= frac{163}{15} =10 frac{13}{15}$

$x+4 frac{1}{3} =7 frac{3}{9}$
$x+ frac{13}{3} = frac{22}{3}$
$x= frac{22}{3} - frac{13}{3}$
$x= frac{9}{9} =1$

$4 frac{1}{2} -y=2 frac{1}{8}$
$frac{9}{2} -y= frac{17}{8}$
$y= frac{9}{2} - frac{17}{8}$
$y= frac{36-17}{8}$
$y= frac{19}{8} =2 frac{3}{8}$

$y-5 frac{3}{7} = frac{1}{14}$
$y- frac{38}{7} = frac{1}{14}$
$y= frac{38}{7} + frac{1}{14}$
$y= frac{76+1}{14}$
$y= frac{11}{2} =5 frac{1}{2}$

$y+13 frac{1}{4} =2 frac{4}{8}$
$y+ frac{53}{4} =2 frac{2}{4}$
$y+ frac{53}{4} = frac{10}{4}$
$y= frac{10}{4} - frac{53}{4}$
$y=- frac{43}{4} =-10 frac{3}4}$
