Answer 2

Ответ:

240/(21х-99) = 5

21х - 99 = 240/5

21х - 99 = 48

21х = 99+48

21х = 147

х = 147/21

х = 7.

240/(147-99) = 5.

              5 = 5

Answer 3

It appears that you've provided an equation that involves some mathematical operations. Let's break down the equation and try to solve for the variable, which I assume is "x."

The equation you've provided is:

240 / (21x - 99) = 5

To solve for "x," you can follow these steps:

1. Start by multiplying both sides of the equation by (21x - 99) to isolate the denominator on the left side:

   240 = 5(21x - 99)

2. Now, distribute 5 on the right side:

   240 = 105x - 495

3. Next, add 495 to both sides of the equation to isolate the term with "x" on the right side:

   240 + 495 = 105x

4. Combine the constants on the left side:

   735 = 105x

5. Finally, divide both sides by 105 to solve for "x":

   x = 735 / 105 x = 7

So, the solution for the equation is x = 7.
