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+5n=8n
7n - 2 plus 3n plus 4 equals?
7n - 2 + 3n + 4 = 7n + 3n - 2 + 4 = 10n + 2 which can be simplified to 2(5n +1)
2n plus 3n plus 7 equals -41?
first combine like terms and 5n+7=-41 add -7 to both sides 5n=-48 n=-48/5
What is 3n2 plus 5n plus 2?
(3n+2)(n+1)
How do you simplify the expression -5n --3n?
-2
What is the answer to 5n-7 equals 3n plus 2?
4n
What is 3n plus 5n?
3n+5n=8n
What is 3n plus 2n equals 7 plus 4n?
3n + 2n = 7 + 4n 5n = 7 + 4n 5n - 4n = 7 n = 7
-3n plus 5n plus 4 equals -4 solve for n?
-3n+5n+4 = -4 2n = -4-4 2n = -8 n = -4
What does n equal 3n plus 2n equals 25?
3n + 2n = 25 5n = 25 n = 5
What is 2n plus 3n?
5n = 2n + 3n .
