k − 12 < 3
just add 12 to both sides
k < 15
just add 12 to both sides
k < 15
1. Start with the given inequality: k - 12 < 3.
2. To isolate the variable k, add 12 to both sides of the inequality:
k - 12 + 12 < 3 + 12.
This simplifies to: k < 15.
3. Now we have the inequality k < 15, which means k is any value that is less than 15.
So, any value of k that is less than 15 will make the inequality k - 12 < 3 true. The two specific values of k could be any number less than 15. For example, k = 10 and k = 14 are both valid solutions.
