№5. Решите уравнение: 1)-6x=48; 3) -1,6x=-6,4; 5) -$$\frac{4}{9}$$x=-$$\frac{1}{7}$$; 2) 0,8x=-3,2; 4) $$\frac{1}{7}$$x=-$$\frac{3}{14}$$; 6) -2$$\frac{1}{4}$$x=\frac{9}{16}$$

1. -6x = 48

   x = 48 : (-6)

   x = -8

2. 0,8x = -3,2

   x = -3,2 : 0,8

   x = -4

3. -1,6x = -6,4

   x = -6,4 : (-1,6)

   x = 4

4. $$\frac{1}{7}$$x = -$$\frac{3}{14}$$

   x = -$$\frac{3}{14}$$ : $$\frac{1}{7}$$

   x = -$$\frac{3}{14}$$ * $$\frac{7}{1}$$

   x = -$$\frac{3}{2}$$

   x = -1$$\frac{1}{2}$$

5. -$$\frac{4}{9}$$x = -$$\frac{1}{7}$$

   x = -$$\frac{1}{7}$$ : (-$$\frac{4}{9}$$)

   x = -$$\frac{1}{7}$$ * (-$$\frac{9}{4}$$)

   x = $$\frac{9}{28}$$

6. -2$$\frac{1}{4}$$x = $$\frac{9}{16}$$

   -$$\frac{9}{4}$$x = $$\frac{9}{16}$$

   x = $$\frac{9}{16}$$ : (-$$\frac{9}{4}$$)

   x = $$\frac{9}{16}$$ * (-$$\frac{4}{9}$$)

   x = -$$\frac{1}{4}$$

Ответ: 1) -8; 2) -4; 3) 4; 4) -1$$\frac{1}{2}$$; 5) $$\frac{9}{28}$$; 6) -$$\frac{1}{4}$$
