    In the given problem, we know that y is directly proportional to x.

    We also know the direct variation formula.

    y = kx

    Now we need to substitute the value of x and y and find out the value of k. So

    14 = 8k

    Then

    k = 8/14

    = 4/7

    Now in a new equation if we put the value of K and another value of x, then we can find the value of y.

    y = (4/7) * 12

    = 48/7
