7n + 1 = 6n + 8 7n=6n+7 (minus 1 from each side) n=7 (7n-6n equals n, you are left with n=7)
5n + 3 = 14 - 6n <=> 5n +6n = 14 - 3 <=> 11n = 11 => n = 11/11 = 1
6n/10=3 6n=30 n=5
6n = 42 n = 42/6 n = 7
6n=24 you divide both sides by 6 to leave n by itself. the answer is 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)
5n + 3 = 14 - 6n <=> 5n +6n = 14 - 3 <=> 11n = 11 => n = 11/11 = 1
21
6n/10=3 6n=30 n=5
6n = 12 n = 2
3(3n - 1)(n + 1)
If: -6n-2n = 16 Then: n = -2
-5=6n+7 -5-7=6n+7-7 -12=6n -12/6=6n/6 -2=n
6n-1 = 5
The LCM of 4n and 6n is 12n.
6n = 42 n = 42/6 n = 7
6n+3=15 6n+3-3=15-3=12 6n = 12 n=12/6 = 2
