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

7n + 2 = 4n + 17Subtract 2 from each side:7n = 4n + 15Subtract 4n from each side:3n = 15Divide each side by 3:n = 5
(7n - 4)(n + 3)
10n + 3 = 7n + 53n = 2n = 2/3
-7n2 + 74n + 33 = -7n2 + 77n - 3n + 33 = -7n*(n - 11) - 3*(n - 11) = =(-7n - 3)*(n - 11) = -(7n +3)*(n - 11)

7n + 3 = 59 7n = 56 Subtract 3 from BOTH sides n = 8 Divide by 7 on BOTH sides to isolate n
3n + 3(6 + 7n) = 3n + 18 + 21n = 24n + 18

It is 2n^3 + 7n^2 - 13n + 3
7n + 2 = 4n + 17Subtract 2 from each side:7n = 4n + 15Subtract 4n from each side:3n = 15Divide each side by 3:n = 5
(7n - 4)(n + 3)
Simplifying 7n + 3 = 0 Reorder the terms: 3 + 7n = 0 Solving 3 + 7n = 0 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + 7n = 0 + -3 Combine like terms: 3 + -3 = 0 0 + 7n = 0 + -3 7n = 0 + -3 Combine like terms: 0 + -3 = -3 7n = -3 Divide each side by '7'. n = -0.4285714286 Simplifying n = -0.4285714286 or n = -3/7
n = 3Solution:7n/21 = 17n = 1 * 217n = 21n = 21/7n = 3
