Найдите корень уравнения: a) (18x - 11) - (10x + 6) = 6x; б) (0.3y + 1.1) - (0.5y + 1) = 5.6 - y

a) (18x - 11) - (10x + 6) = 6x 18x - 11 - 10x - 6 = 6x 8x - 17 = 6x 8x - 6x = 17 2x = 17 x = \(\frac{17}{2}\) x = 8.5 **Ответ: x = 8.5** б) (0.3y + 1.1) - (0.5y + 1) = 5.6 - y 0.3y + 1.1 - 0.5y - 1 = 5.6 - y -0.2y + 0.1 = 5.6 - y -0.2y + y = 5.6 - 0.1 0.8y = 5.5 y = \(\frac{5.5}{0.8}\) y = \(\frac{55}{8}\) y = 6.875 **Ответ: y = 6.875**
