Answer:
Go by the one step as accurately as possible to find the missing value you are looking for. Isolate variables as often as possible.
Let's say we have this equation...
5x = 15
But what if it was more than that?
Think, what times 5 is 15?
Three.
And now the problem is solved.
When it comes to future problems with one step, don't sweat. Find out what the question is asking, then solve for the variable or what you need to find based off of the result and given value.
You can also ask me, and I will see what I can do.
