would it be A

anonymous · Answer

weird. im a bit confused. one sec

anonymous · Answer

WAIT!!! C

anonymous · Answer

sure?

anonymous · Answer

A and D are pretty much the same...

anonymous · Answer

yup right ok ima go with c

anonymous · Answer

you could write 
$$x+5=6 $$ or $$x+5=−6 $$ as a first step and then solve

radar · Answer

since both sides are perfect squares, take the square root of both sides getting:
x+5 = 6     then solve for x.

radar · Answer

Yes, you have already done that, very good ify214.

mathmate · Answer

A and D are essentially the same, but A is more logical and precise, IMHO.
