№7. Решите уравнение: 7 a) 37 + x = 39 200 4 б) 24 25 7 X 32 ) 33 + x = 39 -x -176=2 23 25 25 16 + 33 4 200 1 33

a) 37\(\frac{7}{200}\) + x = 39\(\frac{4}{200}\) x = 39\(\frac{4}{200}\) - 37\(\frac{7}{200}\) x = 2 - \(\frac{3}{200}\) б) (24\(\frac{4}{25}\) - x) - 17\(\frac{6}{25}\) = 2\(\frac{23}{25}\) 24\(\frac{4}{25}\) - x = 2\(\frac{23}{25}\) + 17\(\frac{6}{25}\) 24\(\frac{4}{25}\) - x = 19\(\frac{29}{25}\) 24\(\frac{4}{25}\) - x = 20\(\frac{4}{25}\) x = 24\(\frac{4}{25}\) - 20\(\frac{4}{25}\) x = 4 в) \((\frac{32}{33}\) - x) + \(\frac{16}{33}\) = 2\(\frac{1}{33}\) \(\frac{32}{33}\) - x = 2\(\frac{1}{33}\) - \(\frac{16}{33}\) \(\frac{32}{33}\) - x = \(\frac{67}{33}\) - \(\frac{16}{33}\) \(\frac{32}{33}\) - x = \(\frac{51}{33}\) \(\frac{32}{33}\) - x = 1\(\frac{18}{33}\) x = \(\frac{32}{33}\) - 1\(\frac{18}{33}\) x = -\(\frac{86}{33}\)

Ответ: a) x = 2\(\frac{3}{200}\); б) x = 4; в) x = -\(\frac{86}{33}\)
