6n+3=15 6n+3-3=15-3=12 6n = 12 n=12/6 = 2
21
6n + 17 = 5 subtract 17 from both sides 6n = -12 divide both sides by 6 n = -2 (negative 2)
6n - 2n + 2 = n - 11 4n - n = -11 - 2 3n = -13 n = -13/3 = -4.3333
it equals -15
6n = 12 n = 2
If: -6n-2n = 16 Then: n = -2
-5=6n+7 -5-7=6n+7-7 -12=6n -12/6=6n/6 -2=n
6n+3=15 6n+3-3=15-3=12 6n = 12 n=12/6 = 2
21
6n + 17 = 5 subtract 17 from both sides 6n = -12 divide both sides by 6 n = -2 (negative 2)
If 6n = 1 then n = 1/6.
6n/10=3 6n=30 n=5
6n - 2n + 2 = n - 11 4n - n = -11 - 2 3n = -13 n = -13/3 = -4.3333
-6n + 2 - 5n = -9Combine like terms:-11n + 2 = -9Subtract 2 from each side:-11n = -11Divide both sides by -1:n = 1
7n + 1 = 6n + 8 7n=6n+7 (minus 1 from each side) n=7 (7n-6n equals n, you are left with n=7)
The LCM of 4n and 6n is 12n.
