Answer 1

Ответ:

10

Пошаговое объяснение:

5,6x+32+0,4x-6=86

6x+26=86

6x=86-26

6x=60

x=10

Answer 2

To solve the given equation for the variable "x," follow these steps:

Given equation: 8(0.7x + 4) + 2(0.2x - 3) = 86

Step 1: Distribute the coefficients inside the parentheses: 5.6x + 32 + 0.4x - 6 = 86

Step 2: Combine like terms on both sides of the equation: 6x + 26 = 86

Step 3: Subtract 26 from both sides to isolate the term with "x": 6x = 60

Step 4: Divide both sides by 6 to solve for "x": x = 10

So, the solution to the equation is x = 10.
