520 Решите уравнение: a) x = 1; в) а = 1; д) x = ; e) y =

Ответ: а) x = \(\frac{3}{2}\), б) y = \(\frac{62}{51}\), в) a = \(\frac{10}{3}\), г) b = \(\frac{183}{104}\), д) x = 1, e) y = 1

а) \(\frac{2}{3}\)x = 1

x = 1 : \(\frac{2}{3}\)

x = \(\frac{3}{2}\)

б) \(\frac{51}{62}\)y = 1

y = 1 : \(\frac{51}{62}\)

y = \(\frac{62}{51}\)

в) \(\frac{3}{10}\)a = 1

a = 1 : \(\frac{3}{10}\)

a = \(\frac{10}{3}\)

г) \(\frac{104}{183}\)b = 1

b = 1 : \(\frac{104}{183}\)

b = \(\frac{183}{104}\)

д) \(\frac{7}{25}\)x = \(\frac{7}{25}\)

x = \(\frac{7}{25}\) : \(\frac{7}{25}\)

x = 1

e) \(\frac{13}{6}\)y = \(\frac{13}{6}\)

y = \(\frac{13}{6}\) : \(\frac{13}{6}\)

y = 1

Ответ: а) x = \(\frac{3}{2}\), б) y = \(\frac{62}{51}\), в) a = \(\frac{10}{3}\), г) b = \(\frac{183}{104}\), д) x = 1, e) y = 1
