so not a

jwheele1 · Answer

6x^3-9x=9x-6x^3

make x a number.....lets say 0.

6(0)-9(0)=9(0)-6(0)
0        -0  = 0 - 0
0 = 0
true so not D

jwheele1 · Answer

3x^2+14y=14y+3x^2

make x a number (0)
make y a different number (1)

3(0)+14(1)=14(1)+3(0)
0 +       14  =  14 +0
14       =     14

true so not C

@Directrix  apologize, I thought that's what I was doing by working out the steps.  Ill wait for a reply for each step in the future. I do not condone giving a straight forward answer ever.

@jwheele1   I hear ya. It is tough and frustrating to help the Askers when they post a question and disappear. When the Asker is "live" on the thread, some are shy and will not respond.
