choices?

Answer 2

I am sorry I don't know, do you have any guess at what it could be? If so tell me.

Answer 4

I worked it down to
9*1/4a=-6*9
But now I'm lost.. Unless the equation is supposed to be
9*1/4a=-6

Answer 5

You have to keep anything that is in the absolute value bars, in them until they are alone on one side of the = sign

Answer 6

So it should be something like this
-9+|1/4a|=-3
-9 +9 |1/4a|=-3 +9
|1/4a|=6
1/4a*4/1 = 6 * 4/1
a = 24

Answer 7

so now I would just substitute to make sure I am right
-9 +|1/4a|=-3
-9 + |1/4(24)|=-3
-9 + |6| = -3
-9 + 6 = -3
So the answer is a = 24
