Answer: n=11
Step-by-step explanation:
(n+4)/10 = (n-8)/2
multiply both sides by 10
n+4 = (n-8)/2*10
cancel
n+4=(n-8)*5
n+4=5(n-8)
multiply
n+4=5n-40
subtract both sides by 5n
n-5n+4=-40
subtract both sides by 4
n-5n=-40-4
subtract the like terms
-4n=-44
cancel the negatives
4n=44
divide each side by 4
n=11
Answer:
We can solve using cross products
(n+4) * 2 = 10 * ( n-8)
Distribute
2n+8 = 10n -80
Subtract 2n from each side
2n+8-2n = 10n-80-2n
8 = 8n-80
Add 80 to each side
8+80= 8n-80+80
88 = 8n
Divide each side by 8
88/8 = 8n/8
11 = n
