Depends on what you mean by 1/4x (see below)
Step-by-step explanation:

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
I=prt. Sub in what you know: I=12,000(.015)(4). Multiply: I=12,000(.06). Multiply again: I=720. The investment earned $720 :)
