12+6/7n=-25n add 25n and subtract 12 on both sides
25 6/7n=-12 convert to improper fraction
181/7n=-12 multiply both sides by seven to clear the fraction
181n=-84 divide both sides by 181 to get your answer
n= -.46 hope that helps..

Answer:
180 hours
Step-by-step explanation:
Surfer #1 takes a capsule every 6 hours, but this is also equal to 2 capsules every 12 hours. Surfer #2 takes 1 capsule every 12 hours. Thus, both surfers take a total of 3 capsules every 12 hours.
By dividing 45 total capsules they need to consume by 3, the number of capsules the surfers consume every 12 hour, you get the total number of hours times 12 it takes for them to consume 45 capsules. 45 / 3 = 15, so it takes 15 * 12 hours for them to consume 45 capsules. This is equal to 180 total hours.
