[48 +50x100:(28:a+6)-14] x [(50 - 4 x 5)+(143-4 x 6)]=42316

[48 +50x100:(28:a+6)-14] x [(50-20)+(143-24)]=42316

[48 +50x100:(28:a+6)-14] x (30+119)=42316

[48 +50x100:(28:a+6)-14] x 149=42316

48 +50x100:(28:a+6)-14=42316:149

48 +50x100:(28:a+6)-14=284

48 +50x100:(28:a+6)=284+14

48 +50x100:(28:a+6)=298

50x100:(28:a+6)=298-48

50x100:(28:a+6)=250

100:(28:a+6)=250:50

100:(28:a+6)=5

28:a+6=100:5

28:a+6=20

28:a=20-6

28:a=14

a=28:14

a=2
