Solve each formula for n.

2n = 4xp-6

3m-n=4s

r/n+2=p

t=100(n+3)

pv/nR=T

8a+2=6b

In the first example, divide both sides of the equation by 2

In the second example, add n to both sides of the equation.

Try these yourself. They aren't that hard. We will be glad to critique your work.

There is no "n" in the last example.

1. 2n=4xp-6

Divide 2 from both sides:

n=2xp-3

2. 3m-n=4s

Subtract 3m from both sides:

-n=-3m+4s

Divide -1 from both sides:

n=3m-4s

For the last one I meant -

8a+2n=6b

If 8a+2n=6b, then

2n = 6b - 8a

n = 3b - 4a

You seem to understand this pretty well.
