Answer 4

for example does D work?
well 3(8)(1)+9=24+9=33 <--both sides would equal
but
3(2)(6)+9=45 <---both sides do not equal
so D is definitely not right

Answer 5

you try the other parts

Answer 6

ok

Answer 7

Let's solve for x.
3xy+9=33
Step 1: Add -9 to both sides.
3xy+9+−9=33+−9
3xy=24
Step 2: Divide both sides by 3y.
