Question

4/х-4=-5 решить уравнение​

Answer 1

Ответ:3.2

Объяснение: 4/(x - 4) = -5           ОДЗ: х ≠ 4

    4 = -5(х - 4)

    4 = -5х + 20

    5х = 20 - 4

     х = 16:5

     х = 3,2

Answer 2

To solve the equation $\frac{4}{x} - 4 = -5$, follow these steps:

Step 1: Eliminate the fraction by multiplying both sides of the equation by $x$: $x \cdot \left(\frac{4}{x} - 4\right) = x \cdot (-5)$

Step 2: Simplify the equation: $4 - 4x = -5x$

Step 3: Get all $x$ terms on one side and the constant terms on the other side: $4x - 5x = -4$

Step 4: Combine the $x$ terms on the left side: $-x = -4$

Step 5: Solve for $x$ by dividing both sides by -1: $x = 4$

So the solution to the equation is $x = 4$.
