Alright, let's break it down step by step!
Imagine you have two friends, let's call them W and U. They are going on a treasure hunt together, and you need to figure out where W is on the map. You know that to find W, you need to add U's location to where they started from.
So, the equation 'v = w + u' is like saying: 'The treasure's location (v) is equal to where W started (w) plus where U is located (u)'
Now, to find W, you need to get it by itself on one side of the equation. You can do this by subtracting U from both sides, like this:
w = v - u
Now you have successfully solved the equation for W! You found the location of W by taking the treasure's location and subtracting where U is. That's it! You have cracked the code to find W!
