Răspuns:

• $\bf \red{\underline{a=35~908}}$
• $\bf\purple{\underline{a=10~744}}$
• $\bf \blue{\underline{a=241~347}}$
• $\bf \green{\underline{a = 249~302}}$
• $\bf \pink{\underline{a = 140~123}}$
• $\bf \red{\underline{a = 289~883}}$
• $\bf \purple{\underline{a=85~315}}$
• $\bf \blue{\underline{a = 299~859}}$

Explicație pas cu pas:

$\bf 47~ 584 + 16~ 759 - a = 28~ 435$

$\bf 64~343 - a = 28~ 435$

$\bf 64~343 = 28~ 435+a$

$\bf 64~343 - 28~ 435=a$

$\bf \red{\underline{a=35~908}}$

$---------------$

$\bf 90~ 842 - a = 74~ 370 + 5~ 728$

$\bf 90~ 842 - a = 80~098$

$\bf 90~ 842 = 80~098+a$

$\bf 90~ 842 - 80~098=a$

$\bf\purple{\underline{a=10~744}}$

$---------------$

$\bf 503~ 421 - 205~ 642 - a = 56~ 432$  

$\bf297~779 - a = 56~ 432$

$\bf 297~779 = 56~ 432+a$

$\bf 297~779 -56~ 432=a$

$\bf \blue{\underline{a=241~347}}$      

$---------------$

$\bf 123~ 234 + 135~ 357 + a = 507~893$

$\bf 258~591 + a = 507~893$

$\bf a = 507~893-258~591$

$\bf \green{\underline{a = 249~302}}$

$---------------$

$\bf a + (14~ 029 + 76~ 343) = 230~ 495$

$\bf a + 90~372= 230~ 495$

$\bf a = 230~ 495- 90~372$

$\bf \pink{\underline{a = 140~123}}$

$---------------$

$\bf a - (53~ 870 + 92~ 146) = 143~ 867$

$\bf a - 146~016 = 143~ 867$

$\bf a = 143~ 867+ 146~016$

$\bf \red{\underline{a = 289~883}}$

$---------------$

$\bf (214~ 987 + 58~ 013) - a = 187~ 685$

$\bf 273~000- a = 187~ 685$

$\bf 273~000 = 187~ 685+a$

$\bf 273~000- 187~ 685=a$

$\bf \purple{\underline{a=85~315}}$

$---------------$

$\bf a - (365~ 478 - 278~ 073) = 212~ 454$

$\bf a -87~405= 212~ 454$

$\bf a = 212~ 454+87~405$

$\bf \blue{\underline{a = 299~859}}$

$---------------$
