I have no other information this is how its in the book how do i even solve for n if theres no numbers.

You don't use numbers. It asks to solve for n.

r=y/n

What the problem is asking you to do is to get n on the left side and all the other variables on the other side. That is "solving for n."

Multiply both sides of the equation by n.

r*n=n*(y/n)

You see that cancels the n on the right.

r*n=y

Now how can we get r to the other side. We can divide both sides by r.

(r*n)/r=y*r

That move cancels the r on the left.

n=y/r and there you have it. You have solved for n in terms of the other variables. Now, whan and if you get numbers, you can put in y and r and solve for n in terms of a number.

i wouldn't of ever figuered that out.
