Решите уравнения: a) (x - 3/5) + 7/4 = 9/5 б) 5/8 + (x - 1/5) = 8/8

а) \( (x - \frac{3}{5}) + \frac{7}{4} = \frac{9}{5} \)

\( x - \frac{3}{5} = \frac{9}{5} - \frac{7}{4} \)

\( x - \frac{3}{5} = \frac{36 - 35}{20} \)

\( x - \frac{3}{5} = \frac{1}{20} \)

\( x = \frac{1}{20} + \frac{3}{5} \)

\( x = \frac{1 + 12}{20} \)

\( x = \frac{13}{20} \)

б) \( \frac{5}{8} + (x - \frac{1}{5}) = \frac{8}{8} \)

\( x - \frac{1}{5} = \frac{8}{8} - \frac{5}{8} \)

\( x - \frac{1}{5} = \frac{3}{8} \)

\( x = \frac{3}{8} + \frac{1}{5} \)

\( x = \frac{15 + 8}{40} \)

\( x = \frac{23}{40} \)

Ответ: а) \( x = \frac{13}{20} \), б) \( x = \frac{23}{40} \)
