Isolate variable k: First, we need to isolate the variable k on one side of the equation. We can do this by subtracting 6k from both sides of the equation to get all the k terms on one side.3k−6k=9+6k−6k
Simplify left side: Now, we simplify the left side by combining like terms, which are the terms with k.(3k−6k)=9−3k=9
Solve for k: Next, we solve for k by dividing both sides of the equation by −3 to isolate k.−3−3k=−39k=−3
