Răspuns :

{[1926/6+218-(800-873/3)]/[10000-5*1000-(8*a+1342)]}=3 321+218-(800-291) / 10000-5000-(8*a+1342)=3
321+218-(800-291) / 5000-(8*a+1342)=3
539-(800-291) / 5000-(8*a+1342)=3
539-509 / 5000-(8*a+1342)=3
30/5000-(8*a+1342)=3
30/x=3 =>x=10
5000-(8*a+1342)=10
8*a+1342=4990
8*a=4990-1342
8*a=3648
a=3648/8
a=456
