Решите линейное уравнение:$$0.5(\frac{1}{4}y+2.1) = -0.5y - 3\frac{1}{4}$$

Преобразуем уравнение:

1. $$0.5(\frac{1}{4}y+2.1) = -0.5y - 3\frac{1}{4}$$
2. $$0.5(\frac{1}{4}y+2.1) = -0.5y - \frac{13}{4}$$
3. $$0.125y+1.05 = -0.5y - 3.25$$
4. $$0.125y + 0.5y = -3.25 -1.05$$
5. $$0.625y = -4.3$$
6. $$y = \frac{-4.3}{0.625}$$
7. $$y = -6.88$$

Ответ: y = -6.88
