no.
Do you know what an open equation is?
Your answer is just an expression of the additive identity.
In fact, all of the choices are open equations.
For the second one,
4a - 5 =12
is clearly false if a=3, since
4*3-5 = 12-5 = 7
In fact, none of the equations has 3 as its solution.
You have some serious homework problems here!
And by that, I mean either
(a) problems with the questions/answers
(b) problems with your typing
PLEASE HELP ME!!!
