y = kx

75 = k * 25

k = 75/25 = 3

y = 3x

25 = 3x

x = 25/3

The value of  x when y = 25 is 25/3.

what is proportion?

A proportion is an equation in which two ratios are set equal to each other.

Given : y=75 and x= 25

So,

75/25= 25/x

75*x= 25*25

75*x=625

x= 625/75

x= 25/3

Hence, the value of x when y =25 is 25/3.
