8n + (5-n) + 13 = 7n + 18
3 + 8n = -58n = -8n = -1
N is 1.
It a a mathematical expression that can be simplified as 7n + 18.
n=77
n = (65 - 25)/8 ie 5
n5n+8n-12n13n-12n = n
2n-5 = 8n+7 Subtract 8n from both sides and add 5 to both sides:- -6n = 12 Divide both sides by -6 to find the value of n:- n = -2
8n + 7 - n - 98 = 7n - 91
(n - 3)(n - 5) = n² - 8n + 15
The GCF is 8. 8(m + n)
if you're asking what n is equal to, the answer is 5. Here's how you find the answer: -n+8n = 35 start off by combining like terms. such as the negative "n" and the 8n as they are both expressed in terms of "n". The negative n with no number in front of it is the same as saying -1n. So it becomes a matter of adding -1 to 8. -1n+8n = 35 7n=35 Then, to isolate n, simply divide both sides by seven (7n)/7= 35/7 n = 5 I hope that helps.
