Answer 2

4)

$x + \dfrac{5}{24} = \dfrac{7}{12}\\\\\\x = \dfrac{7}{12} - \dfrac{5}{24}\\\\\\x = \dfrac{14}{24} - \dfrac{5}{24}\\\\\\x = \dfrac{14-5}{24}\\\\\\x = \dfrac{9}{24}\\\\\\\boxed{x = \dfrac{3}{8}}$

5)

$y + \dfrac{2}{7} = \dfrac{1}{3}\\\\\\y = \dfrac{1}{3} - \dfrac{2}{7}\\\\\\y = \dfrac{7}{21} - \dfrac{6}{21}\\\\\\y = \dfrac{7-6}{21}\\\\\\\boxed{y = \dfrac{1}{21}}$

6)

$x - \dfrac{1}{6} = \dfrac{7}{9}\\\\\\x = \dfrac{7}{9} + \dfrac{1}{6}\\\\\\x = \dfrac{14}{18} + \dfrac{3}{18}\\\\\\\\x = \dfrac{14+3}{18}\\\\\\\boxed{x = \dfrac{17}{18}}$

7)

$y - \dfrac{3}{8} = \dfrac{5}{32}\\\\\\y = \dfrac{5}{32} + \dfrac{3}{8}\\\\\\y = \dfrac{5}{32} + \dfrac{12}{32}\\\\\\y = \dfrac{5+12}{32}\\\\\\\boxed{y = \dfrac{17}{32}}$

8)

$y + \dfrac{2}{5} = \dfrac{1}{2}\\\\\\y = \dfrac{1}{2} - \dfrac{2}{5}\\\\\\y = \dfrac{5}{10} - \dfrac{4}{10}\\\\\\y = \dfrac{5-4}{10}\\\\\\\boxed{y = \dfrac{1}{10}}$
