Question

2) 16,4 - 4,05x = 14,78.​

Answer 1

16,4-4.05х=14,78
-4.05х=14,78-16,4
-4,05х=1,62
-405х=-162 теперь раздели обе части на -81
И ответ
5х=2

Answer 2

To solve for x in the equation 16.4 - 4.05x = 14.78, follow these steps:

1. Start by isolating the variable x on one side of the equation. You can do this by subtracting 16.4 from both sides of the equation to get rid of it on the left side:

   16.4 - 16.4 - 4.05x = 14.78 - 16.4

2. This simplifies to:

   -4.05x = -1.62

3. Now, to solve for x, divide both sides by -4.05:

   (-4.05x) / (-4.05) = (-1.62) / (-4.05)

4. This simplifies to:

   x = 0.4

So, the solution to the equation is x = 0.4.
