Решение уравнений:

1. a) $$\frac{1}{4}x = 8$$ $$\frac{1}{4}x = 8$$ $$x = 8 \times 4$$ $$x = 32$$ <p><strong>Ответ: x = 32</strong></p>
2. б) $$5x - 12,5 = 0$$ $$5x - 12,5 = 0$$ $$5x = 12,5$$ $$x = \frac{12,5}{5}$$ $$x = 2,5$$ <p><strong>Ответ: x = 2,5</strong></p>
3. в) $$3x - 0,6 = x + 4,4$$ $$3x - 0,6 = x + 4,4$$ $$3x - x = 4,4 + 0,6$$ $$2x = 5$$ $$x = \frac{5}{2}$$ $$x = 2,5$$ <p><strong>Ответ: x = 2,5</strong></p>
4. г) $$4x - (7x - 2) = 17$$ $$4x - (7x - 2) = 17$$ $$4x - 7x + 2 = 17$$ $$-3x = 17 - 2$$ $$-3x = 15$$ $$x = \frac{15}{-3}$$ $$x = -5$$ <p><strong>Ответ: x = -5</strong></p>
