Question

2) 8,6(13,4-x) - 40.1=156,1+13,4х​

Answer 1

Ответ:↓↓↓

8,6 * 13,4 - 8,6 * x - 40,1 = 156,1 + 13,4 * x

112,44 - 8,6 * x - 40,1 = 156,1 + 13,4 * x

-8,6 * x - 13,4 * x = 156,1 + 40,1 - 112,44

-22 * x = 83,76

x = 83,76 / -22

x ≈ -3,8

Отже, значення x в рівнянні приблизно дорівнює -3,8.

Answer 2

Let's solve the equation step by step:

1. Distribute the 8 and 6 on the left side of the equation:

   8 * 6 - 8 * (13 - x) - 40.1 = 156.1 + 13.4x

   This simplifies to:

   48 - 8 * (13 - x) - 40.1 = 156.1 + 13.4x

2. Distribute the -8 on the left side:

   48 - 8 * 13 + 8x - 40.1 = 156.1 + 13.4x

   This simplifies to:

   48 - 104 + 8x - 40.1 = 156.1 + 13.4x

3. Combine like terms on both sides of the equation:

   (48 - 104 - 40.1) + 8x = 156.1 + 13.4x

   -96.1 + 8x = 156.1 + 13.4x

4. Move the 13.4x term to the left side by subtracting 13.4x from both sides:

   -96.1 + 8x - 13.4x = 156.1

   -96.1 - 5.4x = 156.1

5. Now, isolate the variable x by adding 96.1 to both sides:

   -5.4x = 156.1 + 96.1

   -5.4x = 252.2

6. Finally, divide both sides by -5.4 to solve for x:

   x = 252.2 / -5.4

   x ≈ -46.74

So, the solution to the equation is approximately x ≈ -46.74.
