Решить уравнение

 

У-2цел5/12=-3цел7/15

Answer 1

У-2цел5/12=-3цел7/15

у-29/12=52/15

60у-116/60=156/60

60у=272/60

у=272/3600

у=17/225

Answer 2

$y-2frac{5}{12}=-3frac{7}{15}$

 

$y-frac{29}{12}=-frac{52}{15}$

 

$y=frac{29}{12}-frac{52}{15}$

 

$y=frac{145-208}{60}=-frac{63}{60}=-frac{21}{20}=-1frac{1}{20}=-1,05$
