-5 plus 9n plus 6 is 1 plus 9n.
2+3n+2+9n would equal 4+12n after adding all like numbers.
it equals -4n
9n-2=7n+50 7n+9n=50+2 16n=52 n= 3.25
n - 10 + 9n - 3 = 10n - 13
-5 plus 9n plus 6 is 1 plus 9n.
(8m - 3n)^2 I assume you mean 'squared' , when you write 'square 2'. Because means raising to the power of '2'. Whereas 'cubing' means raising to the power of '3'. To answer (8m - 3n)(8m - 3n( = 64m^2 - 24mn - 24 mn + 9n^2 = 64m^2 - 48 mn + 9n^2 Done!!!!
9n + n = 10n
9n + 18 = 81 9n = 63 n = 7
15m + 4n - 5m + 9n = 10m + 13n
9n+9=81 9n=72 n=8
12m + 9n - 4 - 10m + 6n = 2m + 15n - 4
8m-48
9n + 12y = 3(3n + 4y)
11m + 6n - 2m + 9n = 9m + 15n or 3(3m + 5n)
The equation N-10 plus 9N-e equals 10N-3. This is a math problem.
2+3n+2+9n would equal 4+12n after adding all like numbers.
