Question

7/10x+3/10x+1/2x+3/2x=8/9+1/9 пример

Answer 1

Ответ:

1/3.

Объяснение:

7/10x+3/10x+1/2x+3/2x=8/9+1/9

(7/10x+3/10x)+(1/2x+3/2x) =8/9+1/9

х + 2х = 1

3х = 1

х = 1:3

х = 1/3.

Answer 2

Объяснение:

$\frac{7}{10x}+\frac{3}{10x}+\frac{1}{2x}+\frac{3}{2x}=\frac{8}{9}+\frac{1}{9}\\\\\frac{7+3+5+15}{10x}=\frac{9}{9}\\\\\frac{30}{10x}=1\\\\10x=30\\\\x=\frac{30}{10}\\\\x=3$
