Answer:
Explanation:
From the law if variation,
x <> y ______(1) ,where <> is known as the constant if proportionality.
x = k/y where k is a constant____(2)
Substitute for the values of x and y to get the k
9 = k/6
Therefore k= 54
To find the value of x, go back to equation 2 and substitute for the values if k and y given and computed.
x = 54/15; reduced to lowest term
x = 18/5
x = 3.6
