Решим линейное уравнение: $$\frac{3}{4} \cdot x + \frac{1}{3} = x : (0,2) + 1,1$$
$$0.75x + \frac{1}{3} = \frac{x}{0.2} + 1.1$$
$$0.75x + \frac{1}{3} = 5x + 1.1$$
$$0.75x - 5x = 1.1 - \frac{1}{3}$$
$$-4.25x = \frac{11}{10} - \frac{1}{3}$$
$$-4.25x = \frac{33-10}{30}$$
$$-4.25x = \frac{23}{30}$$
$$x = \frac{23}{30} : (-4.25)$$
$$x = \frac{23}{30} : (-\frac{425}{100})$$
$$x = \frac{23}{30} \cdot (-\frac{100}{425})$$
$$x = \frac{23}{30} \cdot (-\frac{4}{17})$$
$$x = -\frac{92}{510}$$
$$x = -\frac{46}{255}$$
Ответ: $$-\frac{46}{255}$$
