  x ≥ 16  or  x < 0

Step-by-step explanation:

You want ...

  (x -4)/x ≥ 3/4

  4(x -4) ≥ 3x . . . . . . multiply by 4x (requires x > 0)

  4x -16 ≥ 3x

  x ≥ 16 . . . . . . . . . . add 16-3x

__

For x < 0, multiplying by 4x gives ...

 4(x -4) ≤ 3x

  4x -16 ≤ 3x

  x ≤ 16 . . . . . and x < 0

__

There are two sets of solutions:

  x < 0  or  x ≥ 16

no, because the sides are not congruent
