What is 2n plus 3n?
5n = 2n + 3n .
What is 3n plus 2n equals 7 plus 4n?
3n + 2n = 7 + 4n 5n = 7 + 4n 5n - 4n = 7 n = 7
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 comes first in an equation a variable or a number?
A variable comes after the number 2n+5n=7n
What is 5n minus 20?
(5n - 20) It's a binomial expression in 'n'. Its numerical value depends on the numerical value of 'n'.
What is 2n squared plus 5n plus 2?
That factors to (2n + 1)(n + 2)
How do you solve 1 minus 7n equals 15 minus 5n?
1 - 7n = 15 - 5n Add 5n to each side: 1 - 7n + 5n = 15 -5n + 5n ie 1 - 2n = 15; subtract 1 from each side: -2n = 14 divide both sides by -2: n = -7
5n 6n - 2n?
5n + 6n - 2n
How do you solve 5n 6n-2n?
5n+6n-2n can be solved by combining like terms. Combine 5n and 6n and -2n to get 9n.
6 plus 5N equals 2N-9?
6+5n=2n-9Isolate the variable by subtracting 2n and 6 from both sides.5n-2n=-9-63n=-15n=-5
How do you solve -6n-2n?
5n+6n-2n can be solved by combining like terms. Combine 5n and 6n and -2n to get 9n.
What is 2n plus 3n?
5n = 2n + 3n .
5 times n minus 9 equals 2 times n plus 6?
5n - 9 = 2n + 6 : Add 9 to both sides 5n = 2n + 15 : Subtract 2n from both sides 3n = 15 : Divide both sides by 3 n = 5
What is 3n squared minus 5n minus 4n cubed plus 5n squared plus n plus 7?
Assuming you meant 7n (not just 7 at the end of your question) - first... simplify the equation. Numbers raised to powers get priority - so your new sum is... 5n - 64n + 25n + n + 7n.... This simplifies to... -26n
-5n minus 4p plus 7n plus 2?
-2n - 4p + 2. Without knowing n and p, that's the best you get.
What is 5n plus 7 equals 28 plus 2n?
5n + 7 = 28 + 2n (-2n) 3n + 7 = 28 (-7) 3n = 21 therefore, n = 7
What is 5n plus 1 equals 10 plus 2n?
5n + 1 = 10 + 2n5n - 2n + 1 - 1 = 10 - 1 + 2n - 2n3n = 93n/3 = 9/3n = 3
