Add two rational expressions and then label the constraints of the solution

The video tutorial explains how to determine the least common denominator (LCD) and multiply expressions. It guides through simplifying expressions by combining like terms and identifying constraints on variable values. The process involves multiplying expressions, simplifying them, and understanding the constraints where certain values are not permissible for variables.
