Answer:
Depends on what you mean by 1/4x (see below)
Explanation:
For 1/4(x)
1/4x+5 = 4 -> subtract 5 from both sides
1/4x = -1 -> multiply both sides by 4
x = -4
OR
For 1/(4x)
1/4x+5 = 4 -> subtract 5 from both sides
1/4x = -1 -> cross multiply (-1 = -1/1)
-4x = 1 -> divide both sides by -4
x = -1/4
