Solving an Equation with two VariablesDate: 11/20/95 at 19:55:26 From: Anonymous Subject: algebra The problem is n+n+5=25. How do I do this? It has two variables. I tried doing it by subtracting an "n" but then I realized that then I would have to subtract an "n" from the 25. I also tried subtracting the 5 but then I didn't know what to do with the two "n"'s left. Help!

So you can rewrite the equation as 2n + 5 = 25. Do you see how to solve it now? If you need more help, feel free to write back. -Doctor Jonathan, The Geometry Forum |
