Question

Уравнение 19,56 : (3,2x + 4,95x) = 2.

Answer 1

Ответ:

1,2

Пошаговое объяснение:

19,56 : (3,2х + 4,95х) = 2

19,56 : 8,15х = 2

8,15х = 19,56 : 2

8,15х = 9,78

х = 9,78 : 8,15

х = 1,2

Answer 2

$19.56 \div (3.2x + 4.95x) = 2 \\ 19.56 \div 8.15x = 2 \\ 8.15x = 19.56 \div 2 \\ 8.15x= 9.78 \\ x = 9.78 \div 8.15 \\ x = 978 \div 815 \\ x = 1.2$
