Just translate into symbolism. Use a variable for the unknown number.

n is the number.
25% of a number is subtracted from 3/5 of the number,...
%283%2F5%29n-0.25n,

the result 42,...
%283%2F5%29n-0.25n=42

So solve the equation. First, you need to know how to translate from the description into symbols, as I have done.
