Simplify two rational expressions by subtracting

The video tutorial explains how to simplify the expression 6y/15y - (x-y)/15y. It begins by discussing the importance of having a common denominator when dealing with fractions. The tutorial then demonstrates how to subtract fractions by subtracting the numerators while keeping the denominator the same. An example is provided to illustrate this concept. The video proceeds to simplify the given expression by distributing the negative sign and combining like terms, resulting in the final simplified expression: (7y - x)/15y.

What do you get when you combine 6y and y in the expression?

What is the final simplified form of the expression 7y minus x divided by 15y?
