n ___ = 3 2+5 n = 3(2+5) n = 3(7) n = 21
That would be 18+n. 5+3+2 = 5+3+n 10 = 8 + n 10-8 = n 2 = n and if you substitute 2 for n then you see that 5+3+2 = 5+3+2
seven What does n equal
n-3 is three less than n; 3+n is three more than n They can never be equal
Since you have not defined the term n, it can equal anything. Hence, it would be n+5 at this current state.
(n2 + n)/2 1+2+3+4+5+n= 15+n
If you mean: -3(n+5) = 12 then n works out as -9 because -3(-9+5) = 12
3n + 9 = 3(n + 3)
8+n
no
23+n+5+n=23+5+n+n=28+2nIt depends what n is, once, you find out what n is equal to, plug it in to the equation above in bold.
20 = 5 + n/3 15 = n/3 n = 45
