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 do 3n plus 6 equals -9?
3n + 6 = -9 Subtract 6 from both sides: 3n = -15 Divide both sides by 3: n = -5 Therefore n = -5
3n plus 7 equals 16 means?
3n + 7 = 163n + 7 - 7 = 16 - 73n + 7 - 7 = 16 - 73n = 16 - 73n = 93n/3 = 9/33n/3 = 9/3n = 9/3n = 3Check:3 x 3 + 7 =? 169 + 7 =? 1616 =? 16n=3 is the correct answer.

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 do 3n plus 6 equals -9?
3n + 6 = -9 Subtract 6 from both sides: 3n = -15 Divide both sides by 3: n = -5 Therefore n = -5
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.
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
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
If 3n times 3n equals 36 what does n equal?
3n x 3n = 9n if 9n = 36 then n = 36/9 = 4
3n plus 7 equals 16 means?
3n + 7 = 163n + 7 - 7 = 16 - 73n + 7 - 7 = 16 - 73n = 16 - 73n = 93n/3 = 9/33n/3 = 9/3n = 9/3n = 3Check:3 x 3 + 7 =? 169 + 7 =? 1616 =? 16n=3 is the correct answer.
What is the answer to (2n plus 5)-(-3n-7)(4n-9)?
It is 12n2 + 3n - 58
What is n in 3n times 2 equals 18?
n = 3 3n x 2 = 18 3n x 2 / 2 = 18 / 2 3n = 9 3n / 3 = 9 / 3 n = 3
What is the value of n in this equation 7n-11 n equals 3n plus 9?
7n - 11n = 3n + 9 Collecting all the terms with n on the left, (7-11-3)n = 9 -7n = 9 Divide both sides by -7 to give n = -9/7
