Final answer:
When a constant is multiplied by 3, it doesn't affect the value of other variables in the equation.
Step-by-step explanation:
When the value of k in the equation k = xy is multiplied by 3, the value of y remains the same. This is because k is a constant, so its value does not change regardless of any multiplication. Only x, which is the variable in the equation, could potentially change.
