When is an inequality reversed or preserved

There are only two operations that can reverse an inequality, and they are:

  • Multiplying the inequality by a negative number
  • Dividing the inequality by a negative number

Other operations will preserve the inequality.

So, the solution is as follows:

Add 3 -> Preserve

Subtract -3 -> Preserve

Multiply by 3 -> Preserve

Divide by -3 -> Reverse
