Question

solve N=bv/b+v solve for v

Answer 1

N=bv/b+v

N-v = bv/b

(N-v) = v

// i think you can solve it now.

Answer 2

you lost me on that what happened to the b's

Answer 3

b/b = 1

Answer 4

anything divided by itself is 1.

Answer 5

ok i get that (N-v)=v that is not the last step is it i have a hard time with these

Answer 6

N-v = v

N = v+v

Answer 7

Is it \(\large N = \frac{bv}{b+v}\) or \(\large N = \frac{bv}{b}+v\)

Answer 8

would that be the last step or would it be N=v^2 and wio the first one

Answer 9

2+2 = 2(2)
v+v = 2(?)

Answer 10

good observation @wio. I didn't think of that.

Answer 11

\[ \Large
\begin{array}{rcl}
N &=&\frac{bv}{b+v}\\
N(b+v) &=& bv \\
Nb+Nv &=& bv\\
Nb &=& bv-Nv \\
Nb &=& (b-N)v \\
\frac{Nb}{b-N} &=&v \\

\end{array}
\]

Answer 12

N=2v

Answer 13

so wio your saying that v= Nb/b-N right

Answer 14

Put parenthesis around the denominator.

Answer 15

Otherwise that subtraction will happen at the wrong time.

Answer 16

v=(Nb)/b-N

Answer 17

wrong v=Nb/(b-N)

Answer 18

is there more to this equation

Answer 19

wio is there any more steps to this equation

Answer 20

No.

Answer 21

ok but in the final answer i need the parentheses correct
