What else can I help you with?
If 3n plus 4n equals 42 then n is?
3n + 4n = 42 7n = 42 n = 42/7 n = 6
What is 7n plus 6n-5 equals 4n plus 4?
It is a linear equation in one unknown variable, n. Its solution is n = 1
How do you work out 7n plus 1 equals 6n plus 8?
7n + 1 = 6n + 8 7n=6n+7 (minus 1 from each side) n=7 (7n-6n equals n, you are left with n=7)
What is n if 10n plus 3 equals 7n plus 5?
10n + 3 = 7n + 53n = 2n = 2/3
7n - 2 plus 3n plus 4 equals?
7n - 2 + 3n + 4 = 7n + 3n - 2 + 4 = 10n + 2 which can be simplified to 2(5n +1)
Solve 7n plus 2 equals 4n plus 17?
7n + 2 = 4n + 17Subtract 2 from each side:7n = 4n + 15Subtract 4n from each side:3n = 15Divide each side by 3:n = 5
7n plus 2y-3n plus y equals?
4n + 3y
What is 4n plus 11 minus 7n equals negative 13?
-2.18
What is the answer to 4n plus 11-7n equals -13?
I assume you mean what is the solution for the value of n. 4n+11-7n = -13 -3n = -24 n=8
What is 3n-9 plus 4n equals 8n?
3n - 9 + 4n = 8nCombine like terms:7n - 9 = 8nSubtract 7n from both sides:-9 = n
If 3n plus 4n equals 42 then n is?
3n + 4n = 42 7n = 42 n = 42/7 n = 6
What is the sum of the equation 3n plus 4n equals -14?
3n + 4n = -14 7n /7 = -14 /7 n = -2
What is the operation for 3n plus 18 equals 39-4n?
3n+18 = 39 -4n 3n+4n = 39 -18 7n = 21 n = 3
What is the solution to 6n-4-3 equals 3n plus 10 plus 4n?
6n - 4 - 3 = 3n + 10 + 4n -7 = 7n - 6n + 10 -17 = n
What is 7n plus 6n-5 equals 4n plus 4?
It is a linear equation in one unknown variable, n. Its solution is n = 1
What Is The Answer To This Problem 3n plus 12 equals 7n?
Subtracting 3n from each side gives 12 = 4n or 4n = 12. n = 12/4 n = 3
How do you solve 4n minus 7n equals 21?
4n - 7n = 21(4-7) n =21-3n = 21divide both sides by -3n = -7
