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
9n-2=7n+50 7n+9n=50+2 16n=52 n= 3.25
10n + 3 = 7n + 53n = 2n = 2/3
6 , I hope I'm not doing your homework
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)
2 - 7n = 6therefore 7n = 2 - 6 = -4 and so n = -4/7 Then 5m + 7n = 6.4 becomes 5m - 4 = 6.4 so that 5m = 10.4 and then m = 10.4/5 = 2.08

To find the value of n -7n=63 n=63/-7 n-9 Hence,-9 is the required answer.
7n = 7 divide by 7 on both sides n = 7
7n + 3 = 59 7n = 56 Subtract 3 from BOTH sides n = 8 Divide by 7 on BOTH sides to isolate n
n = 1/7
n = 3Solution:7n/21 = 17n = 1 * 217n = 21n = 21/7n = 3
9n-2=7n+50 7n+9n=50+2 16n=52 n= 3.25
n= 7
n=6
