Explicație pas cu pas:
{[(15*32:40*17+95):25+18:x]-8}*2009-2009=224108, x≠0
={[(204+95):25+18/x]-8}*2009-2009=224108=
=[(299:25+18/x)-8]*2009-2009=224108=
=[(11,96+18/x)-8]*2009-2009=224108=
-transformam 11,96 in fractie zecimala-
=[(299/25+18/x)-8]*2009-2009=224108=
-eliminam parantezele-
=(299/25+18/x-8)*2009-2009=224108=
-aducem la acelasi numitor-
=(99/25+18/x)*2009-2009=224108=
-distribuim 2009 elementelor din paranteza-
=198891/25+36162/x-2009=224108=
-aducem din nou la acelasi numitor-
=148666/25+36162/x=224108=
-mutam constanta in partea dreapta si schimbam semnul acesteia-
36162/x=224108-148666/25
36162/x=5454034/25
-simplificam ecuatia folosind inmultirea pe diagonala-
904050=5454034x
x=452025/2727017, x≠0
x≈0,165758
