Answer 1

Ответ:

Пошаговое объяснение:

18:(1+5х) = 4/3

1+5х = 18 : 4/3

1+5х = 13 1/2

5х = 13 1/2 - 1

5х = 12 1/2

х = 12 1/2 : 5 = 25/2 : 5 = 5/2 = 2 1/2

х = 2 1/2

Answer 2

Ответ:

2.5

Пошаговое объяснение:

$\frac{18}{1+5x}$ = $\frac{4}{3}$

1+5x = 18*3 : 4

1+5x = 13.5

5x = 13.5 - 1

5x = 12.5

x = 12.5 : 5

x = 2.5
