If y = 14 when x = 8, find y when x = 12

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

If y 14 when x=8

so 14/8=y/12

y=21
