5n+2n=7n If the variable is the same, n, then you can add the coefficients, 5 and 2. In General an+bn=(a+b)n FOR A CASE THAT DOES NOT WORK. 5n+2m=5n+2m You cannot combine unlike variables
Assuming you meant 7n (not just 7 at the end of your question) - first... simplify the equation. Numbers raised to powers get priority - so your new sum is... 5n - 64n + 25n + n + 7n.... This simplifies to... -26n
5n=30n=30/5n=6
-5n - (-2) = 27 -5n + 2 = 27 -5n + 2 - 2 = 27 - 2 -5n = 25 -5n/-5 = 25/-5 n = -5
Oh, dude, when you simplify 2n + 3n, you're basically just adding the coefficients in front of the 'n'. So, it's like adding 2 and 3, which gives you 5n. It's not rocket science, just some basic algebra.
If it is: 13m+5n-6m+9n Then simplified it is: 7m+14n

The GCF is 5n.

what does the expresstion 5n represent
5m-5n+5m+5n When simplified: 10m
5n=30n=30/5n=6
-5n - (-2) = 27 -5n + 2 = 27 -5n + 2 - 2 = 27 - 2 -5n = 25 -5n/-5 = 25/-5 n = -5
4 over 5n
5n+4 = -26 5n = -26-4 5n = -30 n = -6
