Решите уравнение: a) $$rac{1}{6} cdot x = 18$$ b) $$7x + 11.9 = 0$$ v) $$6x - 0.8 = 3x + 2.2$$ g) $$5x - (7x + 7) = 9$$

a) $$\frac{1}{6} \cdot x = 18$$ $$ x = 18 \cdot 6$$ $$ x = 108$$ Ответ: $$x = 108$$ b) $$7x + 11.9 = 0$$ $$7x = -11.9$$ $$x = -\frac{11.9}{7}$$ $$x = -1.7$$ Ответ: $$x = -1.7$$ v) $$6x - 0.8 = 3x + 2.2$$ $$6x - 3x = 2.2 + 0.8$$ $$3x = 3$$ $$x = 1$$ Ответ: $$x = 1$$ g) $$5x - (7x + 7) = 9$$ $$5x - 7x - 7 = 9$$ $$-2x = 9 + 7$$ $$-2x = 16$$ $$x = -8$$ Ответ: $$x = -8$$
