Can you explain how to solve this equation...15 equals x divided by 6?

Answer 1

I don't know how much about the number systems do you know. I will assume you are only working with whole numbers.

By division "/", we mean an operation such that a = b/c means b = a x c where "x" is the standard multiplication of whole numbers.

so in this case, your question states 15 = x/6 means x = 15 x 6 = 90 and you are done.
