Answer:
k = 7y / xy^2
Explanation:
To find the value of k, we need to simplify the expression on the left-hand side:
xy^2k = (4xy + 3y) - (4xy - 3y)
xy^2k = (4xy + 3y) - 4xy + 3y
xy^2k = 7y
Now we can divide both sides of the equation by xy^2:
k = 7y / xy^2
The value of k is equal to 7 times y divided by the product of x and y squared.
