I don't know how to begin, how do I get two answers from one given expression? Sorry if I sound dumb but any help will be greatly appreciated! Thanks in advance.Given that \(\displaystyle 10^{2n} \times 5^{4-3n} = 2^x \times 5^y\), express y in terms of n.

Answer: \(\displaystyle x = 2n\), \(\displaystyle y = 4 - n\)
