out of a group of zebras 6/5 times the square root of the number of zebras are playing on the shore of the tank remaining six are quarrelling in the water calculate the total number of zebras

Step-by-step explanation:

(6/5)√x = x - 6

(36/25)x = x² - 12x + 36

0 = x² - 13.44x + 36

x = (13.44 ± √(13.44² - 4(1)(36))) / (2(1))

x = (13.44 ± 6.052569702...) / 2

x = 3.69371... zebras

or

x = 9.74628... zebras

In either case we have some odd fractions of zebras hanging around. This makes me highly suspect that the question is misreported

(x, y)→(x − 8, y − 7)

step-by-step explanation:

enjoy!
