Question 238164
When we have an inequality or equality, we need to isolate the variable in order to find its value.  
.
When we add or sustract from both sides of the inequality, the inequality symbol remains the same.
However, when we multiply or divide a NEGATIVE value on both sides, the inequality symbol changes direction.
.
It also changes direction if we decide to swap one side for the other.
Here are a few examples:
.
Sum operation:
{{{20>-2+k}}}
{{{20+2>k}}}
{{{22>k}}} 
If you decide to swap sides, then you'd say: {{{k<22}}} to maintain the same result.
================
Negative Multiplication operation:
{{{30>-(p/4)}}}
{{{30*(-4)<p}}}
{{{-120<p}}} ...same as to say... {{{p>-120}}}
Positive Multiplication operation:
{{{30>p/4}}}
{{{30*4>p}}}
{{{120>p}}} ...same as to say... {{{p<120}}}
===============================================
Now, let's work on your problem:
{{{-3>-3+k}}} ...add 3 on both sides to leave k alone, you get:
{{{-3+3>k}}}
{{{0>k}}} ...same as to say... {{{k<0}}}
Done!  Keep posting problems if you need more help. :)
