Question

Реши уравнение:
8⋅(5+x)−4x=5x−58

Answer 1

8( 5 + x ) - 4x = 5x - 58
40 + 8x - 4x = 5x - 58
8x - 4x - 5x = - 58 - 40
-1x = - 98
x = 98
Ответ: 98

Answer 2

8*(5 + х) - 4х = 5х - 58

40 + 8х - 4х = 5х - 58

40 + 58 = 5х - 4х

х = 98

Проверим:

8*(5 + 98) - 4*98 = 5*98 - 58

824 - 392 = 490 - 58

432 = 432

Ответ: {98}
