Simplifying an expression like 6y involves reducing it to its simplest form. However, in this case, 6y is already in a simple form, as it consists of a constant (6) multiplied by a variable (y).
To put it simply, 6y indicates that you have six times some unknown value represented by y. Since there are no like terms or additional operations to perform, there is no further simplification necessary.
In algebra, simplification usually becomes significant when you have more complex expressions, such as combining like terms or factoring. In this case, 6y stands alone, making it as simple as it can be.
