Question

13/x-3/x+20=0 хелп 11111

Answer 1

Ответ: x = -0,5.

Объяснение:

13/x - 3/x + 20 = 0 умножаем все на x:

1) 13 - 3 + 20*x = 0;

Выделяем x:

2) 20*x = 3 - 13;

3) x = -10/20 = -0,5.

Answer 2

Ответ:

-0,5

Объяснение:

13/x-3/x= -20

10/x=-20

10= -20x

-20x =10

x= -1/2 ←тут идёт сокрашение 10/20

Answer 3

To solve the equation (13/x) - (3/x) + 20 = 0, follow these steps:

Step 1: Combine the fractions on the left side of the equation by finding a common denominator, which is x in this case.

(13/x) - (3/x) + 20 = 0

[(13 - 3)/x] + 20 = 0

(10/x) + 20 = 0

Step 2: Subtract 20 from both sides of the equation to isolate the fraction term.

(10/x) = -20

Step 3: Multiply both sides of the equation by x to solve for the value of x.

10 = -20x

Step 4: Divide both sides of the equation by -20.

x = 10 / -20

x = -0.5

So, the solution to the equation (13/x) - (3/x) + 20 = 0 is x = -0.5.
