No value e. Any value The OA is D. Can any expert explain this PS question please? Thanks. Hi LUANDATO, Let's take a look at your question. $$2k-9-k=4k+6-3k$$ $$2k-k+9=4k-3k+6$$ $$k+9=k+6$$ $$k+9-k=6$$ $$k-k=6+9$$ $$0=15$$ Which means, k has no value. Therefore, option D is correct. Hope it helps. I am available if you'd like any follow up. _________________ GMAT Prep From The Economist We offer 70+ point score improvement money back guarantee.
