X multiply by 5 + k = 3
x multiply by 3 - k = 1
what is x?

Given :-

To find :-

Solution :-

On writing equations mathematically ,

x(5 + k) = 3

x(3 - k) = 1

Divide these both equations ,

5 + k/ 3 -k = 3/1

Cross multiply ,

5 + k = 3(3 - k)

5 + k = 9 - 3k

4k = 4

k = 4/4

k = 1

On substituting the value of k ,

x = 3/(5 + k)

x = 3/ 5+1

x = 3/6

x = 1/2 = 0.5

Hence the required answer is 1/2.
