Title: Fix exercise: One step equations 0.5

Nice exercise @mwahl! I was wondering if you wanted to show the original expression when you're showing the operation that's being done to both sides. As of now, if the equation is:

x + 3 = 10

The hint will show:

x - 3 = 10 - 3

With this commit, the hint will be:

x + 3 - 3 = 10 - 3

Let me know what you think, open to any ideas you have.
