2n + 19 = -7 2n = -7 - 19 2n = -26 n= -13
-7 = 2n + 19 Subtract 19 from both side -26 = 2n Divide by 2 on both sides n = -13
You can't. 17 + 2n = 21 + 2n gives: 2n = 4 + 2n which gives 0=4 which is not possible so the sum is not solveable.
9 - 5n
2n plus 5 n would be 7n and its impossible to solve the value of n.
Move the 2n over the equals sign. Become 4n (as 6n-2n= 4n) and then if 4n=16 then n=4.
1 + 2 + 4 + ... + 2n = 2n+1 - 1
The answer to 2N-4 time 7N plus 7 equals -10.50. This is a math problem.
3 + 3n = 9 + 2n + 4n n = -2
the answer is 0
n = 1
It is an equation and the value of n is 14
Because n = 101.5
15m + (2n-6m) + 11m = = 15m + 11m + 2n - 6m = 26m - 6m + 2n = 20m + 2n = 2(10m + n)
2n+2n equals 4n
Well, if 6 equals 1 plus five, the 2n you put in the middle must be nothing. Think. n=0 Sorry If it's not right
The value of n is 12.5
This equation has no value, as the value of n could be anything, giving this equation an infinite number of answers. To answer this equation, you either need to know what n is, or have an equals sign.
2n + 4m - 2n + m = 5m
n = -6
