Question

determinati pe a din excercitiu urmator

[ 48+50 x 100 : ( 28: a + 6 ) -14 ] x [ ( 50-4x 5 +(143-  4 x 6 )] =42316

Answer 1

[ 48 + 50 . 100 : ( 28 : a + 3 x 2 ) - 14 ] . [ (50 - 20 ) + ( 143-24)=42316
[48+5000 : (28:a +6)-14] x(30 + 119) =42316
[48+5000:(28:a+6)]x149=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=14
a=2
