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
