Решите уравнение: a) 2/3x = 1; в) 3/10a = 1; д) 7/25x = 7/25; б) 51/62y = 1; г) 104/183b = 1; е) 13/6y = 13/6.

Ответ: a) x=1,5; б) y=62/51; в) а=10/3; г) b=183/104; д) х=1; е) y=1

а) \[\frac{2}{3}x = 1\] \[x = 1 : \frac{2}{3}\] \[x = 1 \cdot \frac{3}{2}\] \[x = \frac{3}{2} = 1,5\]

б) \[\frac{51}{62}y = 1\] \[y = 1 : \frac{51}{62}\] \[y = 1 \cdot \frac{62}{51}\] \[y = \frac{62}{51}\]

в) \[\frac{3}{10}a = 1\] \[a = 1 : \frac{3}{10}\] \[a = 1 \cdot \frac{10}{3}\] \[a = \frac{10}{3}\]

г) \[\frac{104}{183}b = 1\] \[b = 1 : \frac{104}{183}\] \[b = 1 \cdot \frac{183}{104}\] \[b = \frac{183}{104}\]

д) \[\frac{7}{25}x = \frac{7}{25}\] \[x = \frac{7}{25} : \frac{7}{25}\] \[x = \frac{7}{25} \cdot \frac{25}{7}\] \[x = 1\]

e) \[\frac{13}{6}y = \frac{13}{6}\] \[y = \frac{13}{6} : \frac{13}{6}\] \[y = \frac{13}{6} \cdot \frac{6}{13}\] \[y = 1\]

Ответ: a) x=1,5; б) y=62/51; в) а=10/3; г) b=183/104; д) х=1; е) y=1
