Пошаговое объяснение:

1) 13/5-7/6-x=11/15

x=13/5-7/6-11/15

x=78/30-35/30-22/30

x=21/30=7/10

2)x=9/16+3/4-7/16

x=9/16+12/16-7/16

x=14/16=7/8

Answer 2

$frac{13}{5} - ( frac{7}{6} + x) = frac{11}{15} \ frac{7}{6} + x = frac{13}{5} - frac{11}{15} \ frac{7}{6} + x = frac{39 - 11}{15} \ frac{7}{6} + x = frac{28}{15} \ x = frac{28}{15} - frac{7}{6} \ x = frac{56 - 35}{30} \ x = frac{21}{30} \ x = frac{7}{10}$

$(x - frac{3}{4} ) + frac{7}{16} = frac{9}{16} \ x - frac{3}{4} = frac{9}{16} - frac{7}{16} \ x - frac{3}{4} = frac{2}{16} \ x - frac{3}{4} = frac{1}{8} \ x = frac{3}{4} + frac{1}{8} \ x = frac{6 + 1}{8} \ x = frac{7}{8}$
