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)
3n+5n=8n
It is: 4n-13
A - B = -3n + 2 - (5n - 7) = -3n + 2 - 5n + 7 = 9 - 8n
5n = 2n + 3n .
The given expression is 3n-7 when simplified
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
In verbal expression, "5n" would be read as "five times n" or "five multiplied by n". This indicates that the value of n is being multiplied by 5. For example, if n = 3, then 5n would be equal to 5 x 3, which equals 15.
-3n+5n+4 = -4 2n = -4-4 2n = -8 n = -4
Combine like terms to give 3n + 2
