Question

Y is inversely proportional to x, when Y = 2, x = 4.Find the value of x when Y = 4.

Answer 1

The value of x when y =4 is 2

How to solve for x?

An inverse proportion is represented as:

k = yx

Where

k represents the constant of proportion

When y = 2, x = 4.

So, we have:

k =2 * 4

k = 8

Substitute k = 8 in k = yx

So, we have:

yx = 8

When y = 4, we have:

4x = 8

Divide by 4

x = 2

Hence, the value of x when y =4 is 2
