Write a general formula to describe the variation: x varies jointly with the inverse of the sum of y and z

x = k/(y+z)

Step-by-step explanation:

We need to write a general formula to describe the variation: x varies jointly with the inverse of the sum of y and z

it can be written as

x ∝ 1/(y+z)

or can be written as

x = k/(y+z)

where k is the constant of variation introduced when we remove the ∝ sign.
