Explicație pas cu pas:
[tex]\bf 47~ 584 + 16~ 759 - a = 28~ 435[/tex]
[tex]\bf 64~343 - a = 28~ 435[/tex]
[tex]\bf 64~343 = 28~ 435+a[/tex]
[tex]\bf 64~343 - 28~ 435=a[/tex]
[tex]\bf \red{\underline{a=35~908}}[/tex]
[tex]---------------[/tex]
[tex]\bf 90~ 842 - a = 74~ 370 + 5~ 728[/tex]
[tex]\bf 90~ 842 - a = 80~098[/tex]
[tex]\bf 90~ 842 = 80~098+a[/tex]
[tex]\bf 90~ 842 - 80~098=a[/tex]
[tex]\bf\purple{\underline{a=10~744}}[/tex]
[tex]---------------[/tex]
[tex]\bf 503~ 421 - 205~ 642 - a = 56~ 432[/tex]
[tex]\bf297~779 - a = 56~ 432[/tex]
[tex]\bf 297~779 = 56~ 432+a[/tex]
[tex]\bf 297~779 -56~ 432=a[/tex]
[tex]\bf \blue{\underline{a=241~347}}[/tex]
[tex]---------------[/tex]
[tex]\bf 123~ 234 + 135~ 357 + a = 507~893[/tex]
[tex]\bf 258~591 + a = 507~893[/tex]
[tex]\bf a = 507~893-258~591[/tex]
[tex]\bf \green{\underline{a = 249~302}}[/tex]
[tex]---------------[/tex]
[tex]\bf a + (14~ 029 + 76~ 343) = 230~ 495[/tex]
[tex]\bf a + 90~372= 230~ 495[/tex]
[tex]\bf a = 230~ 495- 90~372[/tex]
[tex]\bf \pink{\underline{a = 140~123}}[/tex]
[tex]---------------[/tex]
[tex]\bf a - (53~ 870 + 92~ 146) = 143~ 867[/tex]
[tex]\bf a - 146~016 = 143~ 867[/tex]
[tex]\bf a = 143~ 867+ 146~016[/tex]
[tex]\bf \red{\underline{a = 289~883}}[/tex]
[tex]---------------[/tex]
[tex]\bf (214~ 987 + 58~ 013) - a = 187~ 685[/tex]
[tex]\bf 273~000- a = 187~ 685[/tex]
[tex]\bf 273~000 = 187~ 685+a[/tex]
[tex]\bf 273~000- 187~ 685=a[/tex]
[tex]\bf \purple{\underline{a=85~315}}[/tex]
[tex]---------------[/tex]
[tex]\bf a - (365~ 478 - 278~ 073) = 212~ 454[/tex]
[tex]\bf a -87~405= 212~ 454[/tex]
[tex]\bf a = 212~ 454+87~405[/tex]
[tex]\bf \blue{\underline{a = 299~859}}[/tex]
