Гость[latex](3 \frac{2}{3} y+ \frac{1}{6} )-3 \frac{7}{12} =1 \frac{1}{6} [/latex]
[latex]3 \frac{2}{3} y =1 \frac{1}{6}- \frac{1}{6} +3 \frac{7}{12}[/latex]
[latex]3 \frac{2}{3} y =4 \frac{7}{12}[/latex]
[latex] \frac{11}{3} y = \frac{55}{12}[/latex]
[latex] y = \frac{55}{12}: \frac{11}{3}[/latex]
[latex] y = \frac{55}{12}* \frac{3}{11}[/latex]
[latex] y = \frac{5}{4}[/latex]
[latex] y = 1,25[/latex]
[latex](7 \frac{3}{16} -5 \frac{1}{4} x)+3 \frac{3}{4} =9 \frac{1}{16} [/latex]
[latex] -5 \frac{1}{4} x =9 \frac{1}{16} -7 \frac{3}{16}-3 \frac{3}{4}[/latex]
[latex] -5 \frac{1}{4} x =9 \frac{1}{16} -7 \frac{3}{16}-3 \frac{12}{16}[/latex]
[latex] -5 \frac{1}{4} x =-1 \frac{14}{16} [/latex]
[latex] -5 \frac{1}{4} x =-1 \frac{7}{8} [/latex]
[latex] \frac{21}{4} x = \frac{15}{8} [/latex]
[latex] x = \frac{15}{8} : \frac{21}{4}[/latex]
[latex] x = \frac{15}{8}* \frac{4}{21}[/latex]
[latex] x = \frac{5}{2}* \frac{1}{7}= \frac{5}{14} [/latex]
