Solve each formula for n.
2n = 4xp-6
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.
Divide 2 from both sides:
Subtract 3m from both sides:
Divide -1 from both sides:
For the last one I meant -
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.
