What is 3n plus 9 equals 7n-15?
n=6
What is the answer to 3 plus 3n equals 9 plus 2n plus 4n?
3 + 3n = 9 + 2n + 4n n = -2
What does 3n equals 15 plus 12 equal to?
3n = 15 + 12 = 27, 27/3 = 9 = n
What is 3n-9 plus 4n equals 8n?
3n - 9 + 4n = 8nCombine like terms:7n - 9 = 8nSubtract 7n from both sides:-9 = n
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
What is 3n plus 9 equals 7n-15?
n=6
What is the answer to 3 plus 3n equals 9 plus 2n plus 4n?
3 + 3n = 9 + 2n + 4n n = -2
What is 15 9 plus 3n?
Assume the expression is: 15 = 9 + 3n Subtract both sides by 9 to get: 15 - 9 = 9 - 9 + 3n 6 = 3n Finally, divide both sides by 3 to get: 6/3 = 3n/3 n = 2
What does 3n equals 15 plus 12 equal to?
3n = 15 + 12 = 27, 27/3 = 9 = n
What is 3n-9 plus 4n equals 8n?
3n - 9 + 4n = 8nCombine like terms:7n - 9 = 8nSubtract 7n from both sides:-9 = n
5n minus 9 equals 2n plus 6?
Subtract 2n from each side: 3n - 9 = 6 Add 9 to each side: 3n = 15 Divide both sides by 3: n = 5 Therefore, n = 5
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 this property 4 plus 9 plus 6 equals 4 plus 9 plus 6?
Commutativity.
