Відповідь:

Покрокове пояснення:

Нехай  спадкоємець  Х  отримає  х Євро , тоді У отримає  3/4 х Євро ,

а  Z  отримає  2/3 х Євро .

   Рівняння :   х + 3/4 х + 2/3 х = 290 000 ;│Х 12

           12х + 9х + 8х = 12 * 290 000 ;

           29х = 12 * 290 000 ;

                х = ( 12 * 290 000 )/29 ;

                х = 120 000 , тоді 3/4 х = 3/4 * 120 000 = 90 000 ( Євро );

          2/3 х = 2/3 * 120 000 = 80 000 ( Євро ) .

  В  -  дь : Х -  120 000 Євро ;  У -  90 000 Євро ; Z -  80 000 Євро .
