The given equation of Inverse Equation is ,
[tex]\implies xy = k [/tex]
We need to find the value of k , when x = 7 and y = 3 . For that substituting the respective values in the equation , we have ,
[tex]\implies 7\times 3 = k \\\\\implies\underline{\underline{ k = 21}} [/tex]
Hence the required answer is 21.
