Identify Operation: Identify the operation needed to isolate k. In the inequality k+3≤7, the number 3 is being added to k. To isolate k, we need to perform the opposite operation, which is subtraction.
Subtract 3: Subtract 3 from both sides of the inequality to isolate k. k+3≤7k+3−3≤7−3k≤4We subtract 3 from both sides to maintain the balance of the inequality.
