To solve the first equation, we have:

|х+7| / 16 = 32 / 25.6

|х+7| = (16 * 32) / 25.6

|х+7| = 512 / 25.6

|х+7| = 20

Now we have two possible equations to solve for x:

1) x + 7 = 20
x = 13

2) x + 7 = -20
x = -27

Therefore, x = 13 or x = -27.

Next, to solve the second equation:

1.8 / |x - 0.9| = 3 / 8.5

|x - 0.9| = (1.8 * 8.5) / 3

|x - 0.9| = 5.1

Now we have two possible equations to solve for x:

1) x - 0.9 = 5.1
x = 6

2) x - 0.9 = -5.1
x = -4.2

Therefore, x = 6 or x = -4.2.

Lastly, to solve the third equation:

6.9 / 11.5 = 5.7 / |x + 0.5|

11.5 / 6.9 = |x + 0.5| / 5.7

1.6667 = |x + 0.5| / 5.7

|x + 0.5| = 1.6667 * 5.7

|x + 0.5| = 9.5

Now we have two possible equations to solve for x:

1) x + 0.5 = 9.5
x = 9

2) x + 0.5 = -9.5
x = -10

Therefore, x = 9 or x = -10.

The last equation:

9.8 / 2.1 = 12.6 / |x - 0.3|

2.1 / 9.8 = |x - 0.3| / 12.6

0.2143 = |x - 0.3| / 12.6

|x - 0.3| = 0.2143 * 12.6

|x - 0.3| = 2.69

Now we have two possible equations to solve for x:

1) x - 0.3 = 2.69
x = 2.99

2) x - 0.3 = -2.69
x = -2.39

Therefore, x = 2.99 or x = -2.39.
