The authors give a new proof of a non-uniform analog of the Ray-Chaudhuri-Wilson inequality known as Frankl-Ray-Chaudhuri-Wilson inequality. Their proof is inspired by the so-called ``system of linear equations'' method invented by Ramanan. The authors also give a complete classification of the extremal case using the framework of quasi-polynomial semilattices.
