Question

помогите пожалуйста номер 1134

Answer 1

1)
$frac{ frac{2}{15} }{ frac{1}{5} x - frac{1}{3} } - frac{1}{12} = frac{1}{24} \ frac{ frac{2}{15} }{ frac{1}{5} x - frac{1}{3} } = frac{1}{24} + frac{1}{12} \ frac{ frac{2}{15} }{ frac{1}{5} x - frac{1}{3} } = frac{3}{24} \ frac{ frac{2}{15} }{ frac{1}{5} x - frac{1}{3} } = frac{1}{8} \ frac{1}{5} x - frac{1}{3} = frac{2}{15} div frac{1}{8} \ frac{1}{5} x - frac{1}{3} = frac{16}{15} \ frac{1}{5} x = frac{1}{3} + frac{16}{15} \ frac{1}{5} x = frac{21}{15} \ x = frac{21}{15} div frac{1}{5} \ x = frac{21}{15} times frac{5}{1} \ x = 7$

2)
$frac{ frac{2}{9} }{ frac{5}{9} x - frac{1}{2} } + frac{1}{7} = frac{1}{3} \ frac{ frac{2}{9} }{ frac{5}{9} x - frac{1}{2} } = frac{1}{3} - frac{1}{7} \ frac{ frac{2}{9} }{ frac{5}{9} x - frac{1}{2} } = frac{7 - 3}{21} \ frac{ frac{2}{9} }{ frac{5}{9} x - frac{1}{2} } = frac{4}{21} \ frac{5}{9} x - frac{1}{2} = frac{2}{9} div frac{4}{21} \ frac{5}{9} x - frac{1}{2} = frac{2}{9} times frac{21}{4} \ frac{5}{9} x - frac{1}{2} = frac{7}{6} \ frac{5}{9} x = frac{1}{2} + frac{7}{6} \ frac{5}{9} x = frac{3 + 7}{6} \ frac{5}{9} x = frac{10}{6} \ x = frac{10}{6} div frac{5}{9} \ x = frac{10}{6} times frac{9}{5} \ x = 3$
