Final answer:
The equation that represents an infinite number of solutions when the variable terms are collected on one side of the equal sign is k = 9.
Step-by-step explanation:
The equation that represents an infinite number of solutions when the variable terms are collected on one side of the equal sign is k = 9. This equation means that any value of k that is substituted will satisfy the equation and make it true. Thus, there are infinite solutions.
