Answer:

Step-by-step explanation:
So we have the equation:

And we need to solve for n.
First, let's isolate the n variable. To do so, let's add 17 to both sides:

The left side cancels. Add on the right:

Now, let's multiply both sides by 5:

The left side cancels again. Multiply on the right:

So, our solution is 250.
And we're done!
Checking:
Substitute 250 back for n:

Divide first:

We can rewrite this as:

Subtract:

This is indeed correct!
