I got b=.76, a=2.09 put it all back in and you get 3

no, I mean what do you get when you do this: 2  0.12b  1.2b = 3.

so is that the equation?


yes.

If you want to know what b equals follow these steps:
20.1b1.2b=3 (original)
0.1b1.2b=32 (rearrange things)
1.3b=5 (add each side, negatives cancel out)
5/1.3=b (solve for b)
b=3.85

Is this the answer you were looking for?

no, i got 5/132.


what did u you do? I am confused....

why is Angie always posting things????!!!

you are right I misread your equation. It was suposed to be 0.12 not 0.1. In that case your answer of 5/1.32 is correct. (I am assuming you forgot the decimal in your last post.)

I'm posting things cuz i suck at math.
I did:
20.12b1.2b=3
21.32b=3
1.32b=32
1.32b=5
b= 5/1 divided by 1 32/100
b=5/1 divided by 132/1
b=5/1 * 1/132
b=5/132


If you substitute 5/132 back into the original equation it doesn't work.
You solved and ended up with
1.32b=5
so divide both sides by 1.32 and you get 5/1.32 or 3.79. subsitute it back it in to check your work and it should be correct.
