3n+5n=8n
5n + 12 = 3n Try to get all expressions with n on the left side 5n + 12 - 3n = 3n - 3n 2n + 12 = 0 Try to get rid of 12 on the left side 2n + 12 - 12 = -12 2n = -12 n = -12/2 = -6
(3n+2)(n+1)
It is an algebra expression meaning: 5n+4
7n - 2 + 3n + 4 = 7n + 3n - 2 + 4 = 10n + 2 which can be simplified to 2(5n +1)
To simplify the expression (5n + 6n^4 + 3n - 8n^4 + n), first combine like terms. The terms with (n^4) are (6n^4 - 8n^4 = -2n^4) and the terms with (n) are (5n + 3n + n = 9n). Therefore, the simplified expression is (9n - 2n^4).
3n+5n=8n
It is: 4n-13
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.
A - B = -3n + 2 - (5n - 7) = -3n + 2 - 5n + 7 = 9 - 8n
To simplify the expression (-5n + 6 + 7n), combine the like terms involving (n). The terms (-5n) and (7n) can be added together: (-5n + 7n = 2n). Therefore, the simplified expression is (2n + 6).
The given expression is 3n-7 when simplified
To simplify the expression (-3(6n - 5) + 3n), first distribute (-3) inside the parentheses: (-3 \cdot 6n + 15 + 3n = -18n + 15 + 3n = -15n + 15). Thus, the simplified expression is (-15n + 15).
5n + 12 = 3n Try to get all expressions with n on the left side 5n + 12 - 3n = 3n - 3n 2n + 12 = 0 Try to get rid of 12 on the left side 2n + 12 - 12 = -12 2n = -12 n = -12/2 = -6
3n+18 !
3n + 2n = 7 + 4n 5n = 7 + 4n 5n - 4n = 7 n = 7
-3n+5n+4 = -4 2n = -4-4 2n = -8 n = -4
