Answer 2

Given : x = 4, y = 18. Find y when x = 12.

since y varies with x hence we can say that y = kx.

Where k is a constant.

Now from the given values i,e,

x = 4 ,when y = 12

put the values

12 = 4 k

∴ k = 3.

From the given equation

y = 3x.

put x = 18

y = 3 × 18

y = 54.

So the value of y = 54 when x = 12.
