Question

determinati valoarea lui a din:
[48+50 ori 100:(28:a+3 ori 2)-14] ori [(50-4ori5)+(143-4ori6)]=42 316
VA ROG SA MA AJUTATI E URGENT

Answer 1

[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] x 149=42316
48+5000:(28:a+6)-14=42316:149=284
48+5000:(28:a+6)=284+14=298
5000:(28:a+6)=298-48=250
28:a+6=5000:250=20
28:a=20-6=14
a=28:14=2
