We are given the following equation and want to solve for the unknown variable, n:

To solve for an unknown variable, we want to isolate the variable by doing operations to both sides of the equation:
- This includes adding, subtracting, multiplying, and dividing both sides by the same value
For this equation, we'll divide both sides by 5.7 to isolate the unknown variable n

After dividing both sides by 5.7 and simplifying, we get:

The next step is a bit tedious, but in math, you usually want to have the variable on the LEFT side of the equation after isolation.
After reversing the equation accordingly, we have:

We have a value for n, which is 3.
Let me know if you need any clarifications, thanks!
