How do you solve 3n-6 equals 9?
Let's give it a go:3n - 6 = 9Add 6 to each side of the equation:3n = 15Divide each side by 3:n = 5
Does -9 plus 6 equals 3?
No! It equals 15, but 9-6=3.
How do you get 3 to the power of n plus 2 plus (3 to the power of n plus 3 minus 3 to the power of n plus 1)?
3n+2 + (3n+3 - 3n+1) = 3n+1+1 + (3n+1+2 - 3n+1) = 3*3n+1 + (9*3n+1 - 3n+1)= (3+9-1)*3n+1 = 11*3n+1.
6 times 9 plus 6 plus 9 equals?
(6 x 9) + 6 + 9 = 69
What is -15 equals equals 6 plus?
-9
What is 5n plus 9 equals 2n?
Subract 5n from both sides and you get 9=-3n, then divide bother sides by -3 and you get n= -3
