Решите срочно остался один день!!!!!!!!!!!!!!!!!!!

$9 \frac{1}{5} - (5x - 4 \frac{1}{2} ) \div 11 \frac{1}{4} = 8 \frac{14}{15} \\ - (5x - 4 \frac{1}{2} ) \div 11 \frac{1}{4} =8 \frac{14}{15} - 9 \frac{1}{5} \\ - (5x - 4 \frac{1}{2} ) \div \frac{45}{4} = - \frac{4}{15} \\ - (5x - 4 \frac{1}{2} ) = - \frac{4}{15} \times \frac{45}{4} \\ - 5x = - 3 - 4 \frac{1}{2} \\ - 5x = - 7 \frac{1}{2} \\ x = - \frac{15}{2} \div ( - 5) = \frac{15}{2 \times 5} = \frac{3}{2} \\ x = 1 \frac{1}{2} = 1.5$

$\frac{5}{12} y + 3 \frac{2}{9} + 1 \frac{7}{8} y = 5 \frac{1}{18} \\ 1\frac{5 \times 2 + 7 \times 3}{24} y = 5 \frac{1}{18} - 3 \frac{2}{9} \\ 1 \frac{31}{24} y = 2 \frac{1 - 4}{18} \\ 2 \frac{7}{24} y = 2 - \frac{3}{18} \\ \frac{55}{24} y = 2 - \frac{1}{6} \\ y = 1 \frac{5}{6} \div \frac{55}{24} = \frac{11 \times 24}{6 \times 55} = \frac{4}{5} \\ y = 0.8$
