Answer 1

Пошаговое объяснение:

$\frac{18}{30}-x=\frac{4}{30}+\frac{6}{30}$

$\frac{3}{5}-x=\frac{1}{3}$

$-x=\frac{1}{3}-\frac{3}{5}$

$-x=-\frac{4}{15}$

$x=\frac{4}{15}$

$(\frac{13}{67}+\frac{6}{67})-x=\frac{9}{67}$

$\frac{19}{67}-x=\frac{9}{67}$

$-x=\frac{9}{67}-\frac{19}{67}$

$-x=-\frac{10}{67}$

$x=\frac{10}{67}$

$\frac{10}{15}+(\frac{5}{15}-x)=\frac{14}{15}$

$\frac{10}{15}+(\frac{1}{3}-x)=\frac{14}{15}$

$\frac{10}{15}+\frac{1}{3}-x=\frac{14}{15}$

$1-x=\frac{14}{15}$

$-x=\frac{14}{15} -1$

$\\\\-x=-\frac{1}{15\\}\\x=\frac{1}{15}$

$\frac{34}{60}+\frac{8}{60}+y=\frac{41}{60}+\frac{16}{60}$

$\frac{7}{10}+y=\frac{19}{20} \\y=\frac{19}{20}-\frac{7}{10} \\y=\frac{1}{4} =0,25$

$\frac{64}{70}-(x+\frac{26}{70})=\frac{5}{70} \\\frac{64}{70}-(x+\frac{13}{35})=\frac{1}{14} \\\frac{64}{70}-x-\frac{13}{35}=\frac{1}{14} \\\frac{19}{35}-x=\frac{1}{14} \\-x=\frac{1}{14}-\frac{19}{35}\\-x=-\frac{33}{70} \\x=\frac{33}{70}$

$x+\frac{27}{46}=\frac{35}{46}+\frac{2}{46} \\x+\frac{27}{46}=\frac{37}{46}\\x=\frac{37}{46} -\frac{27}{46} \\x=\frac{5}{23}$
