Answer:

x = -1

Step-by-step explanation:

x-1/2 = x-4/5 is ambiguous (subject to misinterpretation).

It should be written with parentheses or with proper fractions:

  x - 1        x - 4

---------- = ----------

    2             5

Cross multiplying results in 5x - 5 = 2x - 8, or 3x = -3.  Then x = -1
