What is the perimeter of 7n plus 2 plus 6 plus 5n plus 7n plus 3n equals?
22n + 2.
6m plus 5n-4m plus 7n equals?
6m + 5n - 4m + 7n = 2m + 12n
7 times n divided 21 equals 1 what is n?
n = 3Solution:7n/21 = 17n = 1 * 217n = 21n = 21/7n = 3
How do you solve 4n minus 7n equals 21?
4n - 7n = 21(4-7) n =21-3n = 21divide both sides by -3n = -7
.5m plus 7n equals 6.4 2m - 7n equals 6?

What is the perimeter of 7n plus 2 plus 6 plus 5n plus 7n plus 3n equals?
22n + 2.
6m plus 5n-4m plus 7n equals?
6m + 5n - 4m + 7n = 2m + 12n
What is 7n - 2 plus 3n plus 4 simplfied?
Gather like terms. The - 2 and 4; the 7n and 3n. 7n - 2 + 3n + 4 = 10n + 2
What is 2n-4 7n plus 7?
5n + 7 = 28 + 2n (-2n) 3n + 7 = 28 (-7) 3n = 21 therefore, n = 7
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)
How do you factor -7n squared plus 74n plus 33?
-7n2 + 74n + 33 = -7n2 + 77n - 3n + 33 = -7n*(n - 11) - 3*(n - 11) = =(-7n - 3)*(n - 11) = -(7n +3)*(n - 11)
What is 9m plus 6n-3m plus 7n?
This question as written can be taken two ways: 9m + 6n - 3m + 7n = 6m + 13n, or (9m + 6n) - (3m + 7n) = 9m + 6n - 3m - 7n = 6m - n
What is n if 10n plus 3 equals 7n plus 5?
10n + 3 = 7n + 53n = 2n = 2/3
7 times n divided 21 equals 1 what is n?
n = 3Solution:7n/21 = 17n = 1 * 217n = 21n = 21/7n = 3
How do you solve 4n minus 7n equals 21?
4n - 7n = 21(4-7) n =21-3n = 21divide both sides by -3n = -7
How do you work out 7n plus 1 equals 6n plus 8?
7n + 1 = 6n + 8 7n=6n+7 (minus 1 from each side) n=7 (7n-6n equals n, you are left with n=7)
.5m plus 7n equals 6.4 2m - 7n equals 6?
