2.248 Pешите уравнение: a) 1-y = $$\frac{7}{24}$$ + $$\frac{1}{4}$$;

a) 1-y = $$\frac{7}{24}$$ + $$\frac{1}{4}$$;

1 - y = $$\frac{7}{24}$$ + $$\frac{6}{24}$$

1 - y = $$\frac{13}{24}$$

y = 1 - $$\frac{13}{24}$$

y = $$\frac{24}{24}$$ - $$\frac{13}{24}$$

y = $$\frac{11}{24}$$

Ответ: $$\frac{11}{24}$$
