What does it mean if the answer of an equation is 2n-15 = 2n-15?

then all values for n makes the equation true.The solution set is all numbers.I suggest you take another look at your workings. In my exam (nearly 30 years ago) I ended up with k = k, but I hadnt expanded a factor properly. Maybe add the original equation as a comment?......

When solving for n? What is that called?

If both sides of the equation are equal, then all values for n makes the equation true.

The solution set is "all numbers".
