[48+50x100:(28+a+3x2)-14]x[(50-4x5)+(143-4x6)]=42316

[48+5000:(28+a+6)-14]x[(50-20)+(143-24)]=42316

[48+5000:(28+a+6)-14]x(30+119)=42316

[48+5000:(28+a+6)-14]x149=42316

48+5000:(28+a+6)-14=42316:149

48+5000:(28+a+6)-14=284

48+5000:(28+a+6)=284+14

48+5000:(28+a+6)=298

5000:(28+a+6)=298-48

5000:(28+a+6)=250

28+a+6=5000:250

28+a+6=20

28+a=20-6

28+a=14
