№6. Решите уравнение: a)35-x=23$$\frac{23}{27}$$; б)47-x=21$$\frac{14}{29}$$; в) ($$\frac{32}{35}$$)+$$\frac{17}{35}$$=2$$\frac{13}{35}$$

Решим уравнения:

a) 35 - x = 23$$\frac{23}{27}$$

x = 35 - 23$$\frac{23}{27}$$

x = 34$$\frac{27}{27}$$ - 23$$\frac{23}{27}$$

x = 11$$\frac{4}{27}$$

б) 47 - x = 21$$\frac{14}{29}$$

x = 47 - 21$$\frac{14}{29}$$

x = 46$$\frac{29}{29}$$ - 21$$\frac{14}{29}$$

x = 25$$\frac{15}{29}$$

в) ($$\frac{32}{35}$$-x)+$$\frac{17}{35}$$=2$$\frac{13}{35}$$

$$\frac{32}{35}$$ - x = 2$$\frac{13}{35}$$ - $$\frac{17}{35}$$

$$\frac{32}{35}$$ - x = 2$$\frac{13}{35}$$ - $$\frac{17}{35}$$

$$\frac{32}{35}$$ - x = 1$$\frac{48}{35}$$ - $$\frac{17}{35}$$

$$\frac{32}{35}$$ - x = 1$$\frac{31}{35}$$

x = $$\frac{32}{35}$$ - 1$$\frac{31}{35}$$

x = $$\frac{32}{35}$$ - $$\frac{66}{35}$$

x = -$$\frac{34}{35}$$

Ответ: a) 11$$\frac{4}{27}$$; б) 25$$\frac{15}{29}$$; в) -$$\frac{34}{35}$$
