It seems impossible as the information given simply states that -k -18 = -k -18

Explanation:

I have a couple questions.
1. What level of education have you come across this question? Which year?
2. Is this the original question, or have you simplified an equation to this?

#k in (-oo, oo)#

Explanation:

Simplifying the right hand side, the equation becomes:

# -k-18 = -k-18#

which is true for any value of #k#.

So the solution space is the whole of the Real numbers #RR# (or the whole of #CC# if you are so inclined).
