Respuesta:
-1/7 + 3/5 - 74/315 = 2/9
Explicación paso a paso:
resolver para r
-1/7 +3/5 = 16/35
2/9 -16/35 = -74/315
r = -74/315
74/315
[tex] - \frac{1}{7} + \frac{3}{5} - r = \frac{2}{9} \\ r = - \frac{1}{7} + \frac{3}{5} - \frac{2}{9} = - \frac{1 \times 5}{7 \times 5} + \frac{3 \times 7}{5 \times 7} - \frac{2}{9} \\ r = - \frac{5}{35} + \frac{21}{35} - \frac{2}{9} = \frac{21 - 5}{35} - \frac{2}{9} \\ r = \frac{16}{35} - \frac{2}{9} = \frac{16 \times 9}{35 \times 9} - \frac{2 \times 35}{9 \times 35} \\ r = \frac{144}{315} - \frac{70}{315} = \frac{144 - 70}{315 } \\ r = \frac{74}{315} [/tex]
