# Explaining how both sides of this equation are equal Watch

1. Say I have:

(e^x - y / x - e^y) = (y-e^x / e^y - x)

By plugging and chugging numbers in it works, just not sure how.

Just something I came across when studying implicity dy/dx which I never gave more thought originally.

thnx

Think about a common factor in the numerator and the denominator of one side.

3. Multiplying by is essentially just multiplying by 1.
