10n + 3 = 93 Therefore, 10n = 90 n = 90/10 n = 9

It has to be interval notation

7n + 3 = 59 7n = 56 Subtract 3 from BOTH sides n = 8 Divide by 7 on BOTH sides to isolate n

The equation N-10 plus 9N-e equals 10N-3. This is a math problem.

7n + 2 = 4n + 17Subtract 2 from each side:7n = 4n + 15Subtract 4n from each side:3n = 15Divide each side by 3:n = 5

-7n2 + 74n + 33 = -7n2 + 77n - 3n + 33 = -7n*(n - 11) - 3*(n - 11) = =(-7n - 3)*(n - 11) = -(7n +3)*(n - 11)

n(7n-3) = 0 n = 0 or n = 3/7

7n+10

N= 2/5! :)

division n=3

6n - 4 - 3 = 3n + 10 + 4n -7 = 7n - 6n + 10 -17 = n

n2 - 10n + 21 = 0 Two numbers that sum to -10 and multiply to 21 are -3 and -7 So (n - 3)*(n - 7) = 0
