7n = 7
divide by 7 on both sides
n = 7
7n = 245To isolate n, divide both sides of the equation by 7.n = 245 / 7n = 35Check:L.S. = 7nL.S. = 7(35)L.S. = 245R.S. = 245L.S. = R.S.245 = 245The equation is true, so the solution is n = 35.
3n + 4n = -14 7n /7 = -14 /7 n = -2
7n = 28n = 28/7 = 4
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
in an equation it would be 7n>42 (divide both sides by 7) = n>6

7n = 28n = 28/7 = 4
7n + 1 = 6n + 8 7n=6n+7 (minus 1 from each side) n=7 (7n-6n equals n, you are left with n=7)
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
n= 7
in an equation it would be 7n>42 (divide both sides by 7) = n>6
The equation (7n - 8 = 6y + 1) can be rearranged to express (n) in terms of (y) or vice versa. To isolate (n), you can add 8 to both sides to get (7n = 6y + 9), and then divide by 7, resulting in (n = \frac{6y + 9}{7}). Alternatively, you can isolate (y) if needed by rearranging the equation accordingly.
n = 1/7
n(7n-3) = 0 n = 0 or n = 3/7
N would equal 7
