If we have that y varies directly with x by a constant of 3/2, we can pose this as follows:


(y)/(x)=(3)/(2),y=(3)/(2)x

Thus, if the value for y = 14, then we can use the previous relation to find the value of x:


(3)/(2)=(14)/(x)\Rightarrow(x)/(14)=(2)/(3)\Rightarrow x=(2\cdot14)/(3)\Rightarrow x=(28)/(3)\Rightarrow x=9.333333333\ldots.

Then, the value for x = 9.33333... or 91/3:


x=9.333333,x=9(1)/(3)
