Answer 1

$x+\frac{7}{50}=\frac{3}{50}+\frac{27}{50}\\\\x+\frac{7}{50}=\frac{30}{50}\\\\x=\frac{30}{50}-\frac{7}{50} \\\\x=\frac{21}{50}$

Проверка:

$\frac{21}{50} +\frac{7}{50}=\frac{3}{50}+\frac{27}{50}\\\\\frac{21}{50} +\frac{7}{50}=\frac{30}{50}\\\\\frac{30}{50} =\frac{30}{50}$

------------------------------

$\frac{116}{125} -(\frac{41}{125} +x)=\frac{24}{125}\\\\\frac{116}{125} -\frac{41}{125} -x=\frac{24}{125} \\\\-x=\frac{24}{125} -\frac{116}{125} +\frac{41}{125}\\\\-x=-\frac{92}{125}+\frac{41}{125}\\\\-x=-\frac{51}{125} \\\\x=-\frac{51}{125}:(-1) \\\\x=\frac{51}{125}$

Проверка:

$\frac{116}{125}-(\frac{41}{125}+\frac{51}{125} )=\frac{24}{125} \\\\\frac{116}{125} -\frac{92}{125}=\frac{24}{125} \\\\\frac{24}{125}=\frac{24}{125}$

---------------------------------

$\frac{4}{40} +y+\frac{16}{40}= \frac{31}{40} +\frac{6}{40}\\\\\frac{4}{40}+y+\frac{16}{40}=\frac{37}{40}\\\\y=\frac{37}{40}-\frac{4}{40}-\frac{16}{40}\\\\y=\frac{33}{40}-\frac{16}{40} \\\\y=\frac{17}{40}$

Проверка:

$\frac{4}{40}+\frac{17}{40}+\frac{16}{40}=\frac{31}{40} +\frac{6}{40}\\\\\frac{21}{40}+\frac{16}{40}=\frac{37}{40}\\\\\frac{37}{40}=\frac{37}{40}$
