n = 3/2, n = 2
7n + 1 = 6n + 8 7n=6n+7 (minus 1 from each side) n=7 (7n-6n equals n, you are left with n=7)
63
7n
9n-2=7n+50 7n+9n=50+2 16n=52 n= 3.25
To find the value of n -7n=63 n=63/-7 n-9 Hence,-9 is the required answer.
n = 3/2, n = 2
2n plus 5 n would be 7n and its impossible to solve the value of n.
I assume you mean what is the solution for the value of n. 4n+11-7n = -13 -3n = -24 n=8
7n(n−1)
7n - 11n = 3n + 9 Collecting all the terms with n on the left, (7-11-3)n = 9 -7n = 9 Divide both sides by -7 to give n = -9/7
38.The position to value rule is Un= (n2+ 7n - 2)/2 where n = 1, 2, 3, ...38.The position to value rule is Un= (n2+ 7n - 2)/2 where n = 1, 2, 3, ...38.The position to value rule is Un= (n2+ 7n - 2)/2 where n = 1, 2, 3, ...38.The position to value rule is Un= (n2+ 7n - 2)/2 where n = 1, 2, 3, ...
-7n2 + 74n + 33 = -7n2 + 77n - 3n + 33 = -7n*(n - 11) - 3*(n - 11) = =(-7n - 3)*(n - 11) = -(7n +3)*(n - 11)
2-n-7n = 2-8n
n(7n-3) = 0 n = 0 or n = 3/7
7n + 1 = 6n + 8 7n=6n+7 (minus 1 from each side) n=7 (7n-6n equals n, you are left with n=7)
