4)

Answer 1

$(3 frac{2}{3} y+ frac{1}{6} )-3 frac{7}{12} =1 frac{1}{6}$
$3 frac{2}{3} y =1 frac{1}{6}- frac{1}{6} +3 frac{7}{12}$
$3 frac{2}{3} y =4 frac{7}{12}$
$frac{11}{3} y = frac{55}{12}$
$y = frac{55}{12}: frac{11}{3}$
$y = frac{55}{12}* frac{3}{11}$
$y = frac{5}{4}$
$y = 1,25$

$(7 frac{3}{16} -5 frac{1}{4} x)+3 frac{3}{4} =9 frac{1}{16}$
$-5 frac{1}{4} x =9 frac{1}{16} -7 frac{3}{16}-3 frac{3}{4}$
$-5 frac{1}{4} x =9 frac{1}{16} -7 frac{3}{16}-3 frac{12}{16}$
$-5 frac{1}{4} x =-1 frac{14}{16}$
$-5 frac{1}{4} x =-1 frac{7}{8}$
$frac{21}{4} x = frac{15}{8}$
$x = frac{15}{8} : frac{21}{4}$
$x = frac{15}{8}* frac{4}{21}$
$x = frac{5}{2}* frac{1}{7}= frac{5}{14}$
