Question

1,98 : (0,7- 2х)= 4,5

Answer 1

Ответ:

х=0,13

Пошаговое объяснение:

1,98:(0,7-2х)=4,5

0,7-2х=1,98:4,5

0,7-2х=0,44

2х=0,7-0,44

2х=0,26

х=0,26:2

х=0,13

Answer 2

To solve the equation 1.98 / (0.7 - 2x) = 4.5, you'll need to isolate the variable x. Here's how you can do it step by step:

1. Start by multiplying both sides of the equation by (0.7 - 2x) to get rid of the denominator:

   1.98 = 4.5 * (0.7 - 2x)

2. Next, distribute 4.5 on the right side of the equation:

   1.98 = 3.15 - 9x

3. Now, subtract 3.15 from both sides of the equation to isolate the term with x:

   1.98 - 3.15 = -9x

4. Simplify the left side:

   -1.17 = -9x

5. Finally, divide both sides by -9 to solve for x:

   x = (-1.17) / (-9)

Now, calculate the value of x:

x = 0.13 (rounded to two decimal places)

So, the solution to the equation is x ≈ 0.13.
