Answer:

y=28

Explanation:

If y varies inversely as x, we can use the formula y = k/x, where k is a constant. To find the value of k, we can use the given information. When x = 7 and y = 8, we can plug these values into the formula to get 8 = k/7. Solving for k, we find that k = 56. Now, we can use this value of k to find y when x = 2. Plugging x = 2 into the formula, we get y = 56/2 = 28. So, when x = 2, y = 28.
