Solve each formula for n.
2n = 4xp6
3mn=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=4xp6
Divide 2 from both sides:
n=2xp3
2. 3mn=4s
Subtract 3m from both sides:
n=3m+4s
Divide 1 from both sides:
n=3m4s
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.

A=1/2h(b+b) find the hieght if the base is cm and 8cm and the area is 56cm.
