What's your goal here? Please share the instructions that came with the problem. Thx.

Note: You don't have " -3 's " to cancel out. Rather, you have ' -3n ' s ' to cancel out.

"To solve" means to find the value of the variable that makes the equation true.

You have: -3n-1=2-3n-8+5
-3n on the left side equals -3n on the right side, so you may cancel out those terms.
type out what you have left.

Yes. Now combine the 2 and the -8. Type out the entire equation, showing your latest version.

Answer 9

Right -1 is always equal to -1. This tells you that your equation is an identity: It's always true, regardless of the value you give to the variable n.

Answer 10

Reread the original question and determine what you were supposed to do. How would you answer this question?

Answer 11

So n doesn't matter then?

Answer 12

You could put it that way. I would much rather that you say "this equation is an identity b ecause it is true for any value of n."
