Răspuns: [tex]\color{red}\Large \boxed{\bf (2 \cdot a + a): 3 + 1 601 = 2010}[/tex]
Explicație pas cu pas:
[tex]\large \bf 2 324 + 22 : 11 + [(a + 3 + 241\cdot 7 - 392) \cdot 2] : 3 = 3 464[/tex]
[tex]\large \bf 2 324 + 2 + [(a + 3 + 1687 - 392) \cdot 2] : 3 = 3 464[/tex]
[tex]\large \bf 2 324 + 2 + [(a + 3 + 1295) \cdot 2] : 3 = 3 464~~\bigg|\cdot3[/tex]
[tex]\large \bf 6972 + 6 + (a + 3 + 1295) \cdot 2 = 3 464\cdot3[/tex]
[tex]\large \bf 6978 + (a + 3 + 1295) \cdot 2 = 10392[/tex]
[tex]\large \bf (a + 3 + 1295) \cdot 2 = 10392 - 6978[/tex]
[tex]\large \bf (a + 3 + 1295) \cdot 2 = 3414~~\bigg|:2[/tex]
[tex]\large \bf a + 3 + 1295 =1707[/tex]
[tex]\large \bf a = 1707- 3 - 1295[/tex]
[tex]\color{blue}\Large \boxed{\bf a = 409}[/tex]

[tex]\large \bf (2 \cdot a + a): 3 + 1 601 = 3a:3 +1601 = a +1601[/tex]
[tex]\large \bf \xrightarrow[a = 409]{inlocuim~ pe~ a}~a +1601 = 409 + 1601 =\boxed{\bf 2010}[/tex]
