Answer:
x=12
Step by step explanation:
Step by step explanation:Add 9 to both sides :
15 = 2x - 9
15 + 9 = 2x - 9 + 9
Simplify:
24 = 2x

24 = 2x
24/2 = (2x)/2
Result:
x=12

The ratio of the trout with tags that are caught and the total trout with tags is first calculated.
r = 12 trout / 180 trout = 1/15
Then, we divide the number of trouts caught without tag by the value obtained above.
N = (48 - 12) / (1/15) = 540
Then, we add the number obtained above and 180.
T = 540 + 180 = 720
