    The value of x would 6. Y divided by x would get you 3.5, therefore 21 divides by 3.5 is 6.

    y=4.98

    Explanation:

    First, find the constant of proportionality, k.

    y=kx

    21=7k

    k=3

    We now start over and solve for y using the new value of x and the obtained value of k.

    y = (3) (1.66)

    y = 4.98
