I have a reaction occurring at steady state, but the feed is an unknown composition. The reaction occurs according to the balanced equation below:

$1A+2B=>1M+3N$

In the outlet stream, the amount of B is equal to the amount of N$.$ Also, the amount of M is $150\%$ of the amount of $A$ in the outlet stream.

Find the mole fraction of $A$ in the feed stream, and the fractional conversion of $A$ in the reaction.
