Answer:</h2>
<em>K </em>= -3
<h2>
Step-by-step explanation:</h2>
1. Simplify <em>-k-4k to -5k</em>
-5k=3(k-10)-6(k-6)
2. Distribute Parentheses/Expand
-5k=3k-30-6k+36
3.Simplify 3k-30-6k+36 to -3k +6
-5k=-3k+6
4. Add 3k to both sides
-5k+3k=6
5. Simplify -5k+3k to -2k
-2k=6
6. Divide both sides by -2
k=-6/2
7. Simplify 6/2 to 3
k=-3
xis less than or equal to -3
