Homework Help: math

Posted by nae on Thursday, March 29, 2007 at 10:36am.

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.
