Ineed on this one question someone me

So we simplify this and do
5(3a-1)-2(3a+2)=3(a+2)+v
15a-5-6a-4=3a+6+v
add like terms
9a-9=3a+6+v
subtract 6 from both sides and get
9a-15=3a+v
subtract 3a from both sides and get
6a-15=v or 3(2a-5)
so the answers are D,E

or if you want to avoid doing allot of math, you could just figure out which two answer choices are the same (D,E)

Um what? rephrase that ?
