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)
n=3
